v1.1.0 (2019-2-28)

Enhancements

⚙️ TypeScript 3 Support (#3401)

TypeScript test files can now use new syntax features introduced in TypeScript 3.0 and TypeScript 3.3.

⚙️ Enhanced TypeScript Definitions for Client Functions (#3431) by @vitalics

The updated type definitions allow TypeScript compiler to determine client function's return value type. Static typing now warns you when you call wrong methods for the return value.

const getFoo = ClientFunction(() => 42);
const foo    = await getFoo();
foo.match(/foo/);

Prior to v1.1.0, an error occurred during test execution:

$ testcafe chrome tests.ts
 Running tests in:
 - Chrome 72.0.3626 / Windows 10.0.0
 Fixture 1
 √ Test 1
 √ Test 2
 ...
 × Test N
   1) TypeError: foo.match is not a function

With v1.1.0, the TypeScript compiler throws an error before test are started:

$ testcafe chrome tests.ts
  ERROR Cannot prepare tests due to an error.
  Error: TypeScript compilation failed.

  tests.ts (4, 2): Property 'match' does not exist on type 'number'.

• TestCafe correctly processes sourcemaps in stylesheets now (testcafe-hammerhead/#1907)

v1.0.0 (2018-2-7)

Breaking Changes

💥 Test Syntax Validation Disabled: All Input Files Are Executed

Previous versions performed test syntax validation within input script files before executing them. Only files that contained the fixture and test directives were executed.

Starting with v1.0.0, input script files are never validated. This means that TestCafe executes all the scripts you specify as test sources. If you use Glob patterns to specify input test files, please recheck these patterns to avoid unintended file matches.

The --disable-test-syntax-validation command line flag and the disableTestSyntaxValidation option for the runner.run API method that disabled test syntax validation were removed in v1.0.0.

What Has Improved

You can now load tests dynamically without additional customization. The following example illustrates how tests can be imported from an external library.

external-lib.js

export default function runFixture(name, url) {
    fixture(name)
        .page(url);

    test(`${url} test`, async t => {
        // ...
    });
}

test.js

import runFixture from './external-lib';

const fixtureName = 'My fixture';
const url = 'https://testPage';

runFixture(fixtureName, url);

💥 Programming Interface: Multiple Method Calls Prohibited

Previous versions allowed you to call the runner.src, runner.browsers and runner.reporter methods several times to specify multiple test files, browsers or reporters.

const stream = fs.createWriteStream('report.json');

runner
    .src('/home/user/tests/fixture1.js')
    .src('fixture5.js')
    .browsers('chrome')
    .browsers('firefox:headless')
    .reporter('minimal')
    .reporter('json', stream);

Starting with v1.0.0, pass arrays to these methods to specify multiple values.

To use a reporter that writes to a file, add a { name, output } object to an array (see the runner.reporter description for details).

runner
    .src(['/home/user/tests/fixture1.js', 'fixture5.js'])
    .browsers(['chrome', 'firefox:headless'])
    .reporter(['minimal', { name: 'json', output: 'report.json' }]);

What Has Improved

This change was necessary to implement the configuration file in a way that is consistent with the API and command line interface.

💥 Custom Request Hooks: Asynchronous API

Request hook methods became asynchronous in TestCafe v1.0.0.

If the onRequest or onResponse method in your custom hook returns a Promise, TestCafe now waits for this Promise to resolve.

This does not necessarily leads to unexpected behavior, but still be aware of possible side effects.

Since the onRequest and onResponse methods are now asynchronous, add the async keyword to their declarations.

import { RequestHook } from 'testcafe';

class MyRequestHook extends RequestHook {
    constructor (requestFilterRules, responseEventConfigureOpts) {
        super(requestFilterRules, responseEventConfigureOpts);
        // ...
    }

    async onRequest (event) {
        // ...
    }

    async onResponse (event) {
        // ...
    }
}

What Has Improved

You can call asynchronous fs functions, invoke a child_process, or perform asynchronous network requests (to a database or any other server) from inside the hooks.

💥 Custom Reporter Plugins: Asynchronous API

TestCafe v1.0.0 also introduces asynchronous API for reporter plugins.

Similarly to request hooks, if any of the custom reporter's methods (reportTaskStart, reportFixtureStart, reportTestDone or reportTaskDone) returns a Promise, this Promise is now awaited.

Side effects may show up in certain cases.

Since the reporter methods are now asynchronous, add the async keyword to their declarations.

async reportTaskStart (startTime, userAgents, testCount) {
    // ...
},

async reportFixtureStart (name, path, meta) {
    // ...
},

async reportTestDone (name, testRunInfo, meta) {
    // ...
},

async reportTaskDone (endTime, passed, warnings, result) {
    // ...
}

What Has Improved

Reporters can call asynchronous fs functions, invoke a child_process, or perform asynchronous network requests (to send an email, use REST API, connect to a database, etc).

Enhancements

⚙️ Video Recording (#2151)

You can now record videos of test runs in Google Chrome and Mozilla Firefox. To enable video recording, install the FFmpeg library and then do one of the following:

• specify the --video command line flag,

  testcafe chrome test.js --video artifacts/videos/

• call the runner.video API method,

  runner.video('artifacts/videos/');

• specify the videoPath configuration file property (configuration file is also a new feature, see below).

  {
      "videoPath": "artifacts/videos/"
  }

TestCafe records all tests and saves each recording in a separate file. You can change this behavior in video options. You can also customize video encoding parameters.

⚙️ Configuration File (#3131)

TestCafe now allows you to store its settings in the .testcaferc.json configuration file (with support for JSON5 syntax).

{
    "browsers": "chrome",
    "src": ["/home/user/auth-tests/fixture-1.js", "/home/user/mobile-tests/"],
    "reporter": {
        "name": "xunit",
        "output": "reports/report.xml"
    },
    "screenshotPath": "/home/user/tests/screenshots/",
    "takeScreenshotsOnFails": true,
    "videoPath": "/home/user/tests/videos/",
    "pageLoadTimeout": 1000,
    "hostname": "host.mycorp.com"
    // and more
}

Keep the configuration file in the project's root directory from which you run TestCafe.

Settings you specify when you launch tests from the command line and programming interfaces override settings from .testcaferc.json.

See Configuration File for more information.

⚙️ Live Mode (#3215)

We have integrated the testcafe-live module into our main code so you can now use the new live mode.

Live mode keeps the TestCafe process and browsers opened the whole time you are working on tests. Changes you make in code immediately restart the tests. That is, live mode allows you to see test results instantly. See How Live Mode Works.

Use the -L (--live) flag to enable live mode from the command line interface.

testcafe chrome tests/test.js -L

In the API, create a live mode runner with the testcafe.createLiveModeRunner function and use it instead of a regular test runner.

const createTestCafe = require('testcafe');
let testcafe         = null;

createTestCafe('localhost', 1337, 1338)
    .then(tc => {
        testcafe         = tc;
        const liveRunner = testcafe.createLiveModeRunner();
        return liveRunner
            .src('tests/test.js')
            .browsers('chrome')
            .run();
    })
    .then(() => {
        testcafe.close();
    });

⚙️ Custom Reporter API Enhancements (Part of #2753; Pull Request)

• You can now access warnings that appeared during the test run from the reportTestDone method. Use the warnings property of the testRunInfo object.

  async reportTestDone (name, testRunInfo, meta) {
      const warnings    = testRunInfo.warnings;
      const hasWarnings = !!warnings.length;
  
      if(hasWarnings) {
          this.newline()
              .write('Warnings:');
  
          warnings.forEach(warning => {
              this.newline()
                  .write(warning);
          });
      }
  }

• The reportTaskDone method now receives the result parameter that contains information about the number of passed, failed, and skipped tests.

  async reportTaskDone (endTime, passed, warnings, result) {
      this.write(`Testing finished!`)
          .newline()
          .write(`Passed: ${result.passedCount}`)
          .newline()
          .write(`Failed: ${result.failedCount}`)
          .newline();
          .write(`Skipped: ${result.skippedCount}`)
          .newline();
  }

⚙️ Typings for Programming Interface (#3341) by @infctr

TestCafe programming interface now features TypeScript typings.

⚙️ Programming Interface: Simpler API to Write Reports to a File

You no longer need to use fs.createWriteStream to create a stream that writes a report to a file. You can now pass the file name as the runner.reporter parameter.

runnner.reporter('json', 'reports/report.json');

Bug Fixes

• The TestCafe process no longer terminates before the report is written to a file (#2502)

v0.23.1 (2018-11-7)

Enhancements

⚙️ Select Tests and Fixtures to Run by Their Metadata (#2527) by @NickCis

You can now run only those tests or fixtures whose metadata contains a specific set of values.

Use the --test-meta flag to specify values to look for in test metadata.

testcafe chrome my-tests --test-meta device=mobile,env=production

To select fixtures by their metadata, use the --fixture-meta flag.

testcafe chrome my-tests --fixture-meta subsystem=payments,type=regression

In the API, test and fixture metadata is now passed to the runner.filter method in the testMeta and fixtureMeta parameters. Use this metadata to decide whether to run the current test.

runner.filter((testName, fixtureName, fixturePath, testMeta, fixtureMeta) => {
    return testMeta.mobile === 'true' &&
        fixtureMeta.env === 'staging';
});

⚙️ Run Dynamically Loaded Tests (#2074)

You can now run tests imported from external libraries or generated dynamically even if the .js file you provide to TestCafe does not contain any tests.

Previously, this was not possible because TestCafe required test files to contain the fixture and test directives. Now you can bypass this check. To do this, provide the --disable-test-syntax-validation command line flag.

testcafe safari test.js --disable-test-syntax-validation

In the API, use the disableTestSyntaxValidation option.

runner.run({ disableTestSyntaxValidation: true })

Bug Fixes

• Touch events are now simulated with correct touch properties (touches, targetTouches, changedTouches) (#2856)
• Google Chrome now closes correctly on macOS after tests are finished (#2860)
• Internal attribute and node changes no longer provoke MutationObserver notifications (testcafe-hammerhead/#1769)
• The ECONNABORTED error is no longer raised (testcafe-hammerhead/#1744)
• Websites that use Location.ancestorOrigins are now proxied correctly (testcafe-hammerhead/#1342)

v0.23.0 (2018-10-18)

Enhancements

⚙️ Stop Test Run After the First Test Fail (#1323)

You can now configure TestCafe to stop the entire test run after the first test fail. This saves your time when you fix problems with your tests one by one.

Specify the --sf flag to enable this feature when you run tests from the command line.

testcafe chrome my-tests --sf

In the API, use the stopOnFirstFail option.

runner.run({ stopOnFirstFail: true })

⚙️ View the JavaScript Errors' Stack Traces in Reports (#2043)

Now when a JavaScript error occurs on the tested webpage, the test run report includes a stack trace for this error (only if the --skip-js-errors option is disabled).

⚙️ Browsers are Automatically Restarted When They Stop Responding (#1815)

If a browser stops responding while it executes tests, TestCafe restarts the browser and reruns the current test in a new browser instance.
If the same problem occurs with this test two more times, the test run finishes and an error is thrown.

Bug Fixes

• An error message about an unawaited call to an async function is no longer displayed when an uncaught error occurs (#2557)
• A request hook is no longer added multiple times when a filter rule is used (#2650)
• Screenshot links in test run reports now contain paths specified by the --screenshot-pattern option (#2726)

• The switchToIframe function no longer throws an error (#2956)
• TestCafe can now scroll through fixed elements when the action has custom offsets (#2978)
• You can now specify the current directory or its parent directories as the base path to store screenshots (#2975)
• Tests no longer hang up when you try to debug in headless browsers (#2846)
• The removeEventListener function now works correctly when an object is passed as its third argument (testcafe-hammerhead/#1737)
• Hammerhead no longer adds the event property to a null contentWindow in IE11 (testcafe-hammerhead/#1684)
• The browser no longer resets connection with the server for no reason (testcafe-hammerhead/#1647)
• Hammerhead now stringifies values correctly before outputting them to the console (testcafe-hammerhead/#1750)
• A document fragment from the top window can now be correctly appended to an iframe (testcafe-hammerhead/#912)
• Lifecycle callbacks that result from the document.registerElement method are no longer called twice (testcafe-hammerhead/#695)

v0.21.1 (2018-8-8)

Bug fixes

• The RequestLogger.clear method no longer raises an error if it is called during a long running request (#2688)
• TestCafe now uses native methods to work with the fetch request (#2686)

• Response header names specified via the respond function are lower-cased now (testcafe-hammerhead/#1704)
• The cookie domain validation rule on the client side has been fixed (testcafe-hammerhead/#1702)

v0.21.0 (2018-8-2)

Enhancements

⚙️ Test Web Pages Served Over HTTPS (#1985)

Some browser features (like Service Workers, Geolocation API, ApplePaySession, or SubtleCrypto) require a secure origin. This means that the website should use the HTTPS protocol.

Starting with v0.21.0, TestCafe can serve proxied web pages over HTTPS. This allows you to test pages that require a secure origin.

To enable HTTPS when you use TestCafe through the command line, specify the --ssl flag followed by the HTTPS server options. The most commonly used options are described in the TLS topic in the Node.js documentation.

testcafe --ssl pfx=path/to/file.pfx;rejectUnauthorized=true;...

When you use a programming API, pass the HTTPS server options to the createTestCafe method.

'use strict';

const createTestCafe        = require('testcafe');
const selfSignedSertificate = require('openssl-self-signed-certificate');
let runner                  = null;

const sslOptions = {
    key:  selfSignedSertificate.key,
    cert: selfSignedSertificate.cert
};

createTestCafe('localhost', 1337, 1338, sslOptions)
    .then(testcafe => {
        runner = testcafe.createRunner();
    })
    .then(() => {
        return runner
            .src('test.js')

            // Browsers restrict self-signed certificate usage unless you
            // explicitly set a flag specific to each browser.
            // For Chrome, this is '--allow-insecure-localhost'.
            .browsers('chrome --allow-insecure-localhost')
            .run();
    });

See Connect to TestCafe Server over HTTPS for more information.

⚙️ Construct Screenshot Paths with Patterns (#2152)

You can now use patterns to construct paths to screenshots. TestCafe provides a number of placeholders you can include in the path, for example, ${DATE}, ${TIME}, ${USERAGENT}, etc. For a complete list, refer to the command line --screenshot-path-pattern flag description.

You specify a screenshot path pattern when you run tests. Each time TestCafe takes a screenshot, it substitutes the placeholders with actual values and saves the screenshot to the resulting path.

The following example shows how to specify a screenshot path pattern through the command line:

testcafe all test.js -s screenshots -p "${DATE}_${TIME}/test-${TEST_INDEX}/${USERAGENT}/${FILE_INDEX}.png"

When you use a programming API, pass the screenshot path pattern to the runner.screenshots method.

runner.screenshots('reports/screenshots/', true, '${TEST_INDEX}/${OS}/${BROWSER}-v${BROWSER_VERSION}/${FILE_INDEX}.png');

⚙️ Add Info About Screenshots and Quarantine Attempts to Custom Reports (#2216)

Custom reporters can now access screenshots' data and the history of quarantine attempts (if the test run in the quarantine mode).

The following information about screenshots is now available:

• the path to the screenshot file,
• the path to the thumbnail image,
• the browser's user agent,
• the quarantine attempt number (if the screenshot was taken in the quarantine mode),
• whether the screenshot was taken because the test failed.

If the test was run in the quarantine mode, you can also determine which attempts failed and passed.

Refer to the reportTestDone method description for details on how to access this information.

fixture `My fixture`
    .page `http://devexpress.github.io/testcafe/example/`;

test('Take a screenshot of a fieldset', async t => {
    await t
        .click('#reusing-js-code')
        .click('#continuous-integration-embedding')
        .takeElementScreenshot(Selector('fieldset').nth(1), 'my-fixture/important-features.png');
});

This action provides additional customization that allows you to position the center of the screenshot or crop it. For more information, see the documentation.

Note that if the screenshot directory is not specified with the runner.screenshots API method or the screenshots command line option, the t.takeElementScreenshot action will be ignored.

⚙️ Filtering Elements by Their Visibility (#1018)

You can now filter the selector's matching set to leave only visible or hidden elements. To do this, use the filterVisible and filterHidden methods.

import { Selector } from 'testcafe';

fixture `My fixture`
    .page `http://devexpress.github.io/testcafe/example/`;

test('Filter visible and hidden elements', async t => {
    const inputs        = Selector('input');
    const hiddenInput   = inputs.filterHidden();
    const visibleInputs = inputs.filterVisible();

    await t
        .expect(hiddenInput.count).eql(1)
        .expect(visibleInputs.count).eql(11);
});

⚙️ Finding Elements by the Exact Matching Text (#1292)

The current selector's withText method looks for elements whose text content contains the specified string. With this release, we have added the withExactText method that performs search by strict match.

import { Selector } from 'testcafe';

fixture `My fixture`
    .page `http://devexpress.github.io/testcafe/example/`;

test('Search by exact text', async t => {
    const labels       = Selector('label');
    const winLabel     = labels.withExactText('Windows');
    const reusingLabel = labels.withText('JavaScript');

    await t
        .expect(winLabel.exists).ok()
        .expect(reusingLabel.exists).ok();
});

⚙️ Using Decorators in TypeScript Code (#2117) by @pietrovich

TestCafe now allows you to use decorators when writing tests in TypeScript.

Note that decorators are still an experimental feature in TypeScript.
