HyperExecute is a smart test orchestration platform to run end-to-end Playwright tests at the fastest speed possible. HyperExecute lets you achieve an accelerated time to market by providing a test infrastructure that offers optimal speed, test orchestration, and detailed execution logs.

The overall experience helps teams test code and fix issues at a much faster pace. HyperExecute is configured using a YAML file. Instead of moving the Hub close to you, HyperExecute brings the test scripts close to the Hub!

How to run Playwright automation tests on HyperExecute (using Playwright-JS framework)

Pre-requisites

Before using HyperExecute, you have to download HyperExecute CLI corresponding to the host OS. Along with it, you also need to export the environment variables LT_USERNAME and LT_ACCESS_KEY that are available in the LambdaTest Profile page.

Download HyperExecute CLI

HyperExecute CLI is the CLI for interacting and running the tests on the HyperExecute Grid. The CLI provides a host of other useful Tests that accelerate test execution. In order to trigger tests using the CLI, you need to download the HyperExecute CLI binary corresponding to the platform (or OS) from where the tests are triggered:

Also, it is recommended to download the binary in the project's parent directory. Shown below is the location from where you can download the HyperExecute CLI binary:

Configure Environment Variables

Before the tests are run, please set the environment variables LT_USERNAME & LT_ACCESS_KEY from the terminal. The account details are available on your LambdaTest Profile page.

For macOS:

export LT_USERNAME=LT_USERNAME
export LT_ACCESS_KEY=LT_ACCESS_KEY

For Linux:

export LT_USERNAME=LT_USERNAME
export LT_ACCESS_KEY=LT_ACCESS_KEY

For Windows:

set LT_USERNAME=LT_USERNAME
set LT_ACCESS_KEY=LT_ACCESS_KEY

Auto-Split Execution with Playwright-JS

Auto-split execution mechanism lets you run tests at predefined concurrency and distribute the tests over the available infrastructure. Concurrency can be achieved at different levels - file, module, test suite, test, scenario, etc.

For more information about auto-split execution, check out the Auto-Split Getting Started Guide

Core

Auto-split YAML file (yaml/win/.hyperexecute_autosplits.yaml) in the repo contains the following configuration:

globalTimeout: 90
testSuiteTimeout: 90
testSuiteStep: 90

Global timeout, testSuite timeout, and testSuite timeout are set to 90 minutes.   The runson key determines the platform (or operating system) on which the tests are executed. Here we have set the target OS as Windows.

runson: win

Auto-split is set to true in the YAML file.

 autosplit: true

retryOnFailure is set to true, instructing HyperExecute to retry failed command(s). The retry operation is carried out till the number of retries mentioned in maxRetries are exhausted or the command execution results in a Pass. In addition, the concurrency (i.e. number of parallel sessions) is set to 2.

retryOnFailure: true
runson: win
maxRetries: 2

Pre Steps and Dependency Caching

To leverage the advantage offered by Dependency Caching in HyperExecute, the integrity of package-lock.json is checked using the checksum functionality.

cacheKey: '{{ checksum "package-lock.json" }}'

The caching advantage offered by NPM can be leveraged in HyperExecute, whereby the downloaded packages can be stored (or cached) in a secure server for future executions. The packages available in the cache will only be used if the checksum stage results in a Pass.

cacheDirectories:
  - node_modules

The testDiscovery directive contains the command that gives details of the mode of execution, along with detailing the command that is used for test execution. Here, we are fetching the list of Test file scenario that would be further executed using the value passed in the testRunnerCommand

testDiscovery:
  type: raw
  mode: dynamic
  command: grep -nri 'describe' tests  | sed 's/:test.*//'
testRunnerCommand: npx playwright test $test

Running the above command on the terminal will give a list of Test Scenario lines that are located in the Project folder:

Test Discovery Output: tests/test_4.spec.js:4 tests/test_3.spec.js:4 tests/test_2.spec.js:4 tests/test_1.spec.js:4

The testRunnerCommand contains the command that is used for triggering the test. The output fetched from the testDiscoverer command acts as an input to the testRunner command.

testRunnerCommand: npx playwright test $test

Artifacts Management

The mergeArtifacts directive (which is by default false) is set to true for merging the artifacts and combing artifacts generated under each task.

The uploadArtefacts directive informs HyperExecute to upload artifacts [files, reports, etc.] generated after task completion. In the example, path consists of a regex for parsing the directory (i.e. reports that contains the test reports).

mergeArtifacts: true

uploadArtefacts:
  [{
    "name": "Reports",
    "path": ["Reports\\"]
  }]

HyperExecute also facilitates the provision to download the artifacts on your local machine. To download the artifacts, click on Artifacts button corresponding to the associated TestID.

Test Execution

The CLI option --config is used for providing the custom HyperExecute YAML file (i.e. yaml/.hyperexecute_autosplits.yaml). Run the following command on the terminal to trigger the tests in JS files on the HyperExecute grid. The --download-artifacts option is used to inform HyperExecute to download the artifacts for the job.

./hyperexecute --config --verbose yaml/win/.hyperexecute_autosplits.yaml

Matrix Execution with Playwright-JS

Matrix-based test execution is used for running the same tests across different test (or input) combinations. The Matrix directive in HyperExecute YAML file is a key:value pair where value is an array of strings.

Also, the key:value pairs are opaque strings for HyperExecute. For more information about matrix multiplexing, check out the Matrix Getting Started Guide

Core

In the current example, matrix YAML file (yaml/hyperexecute_matrix_sample.yaml) in the repo contains the following configuration:

globalTimeout: 90
testSuiteTimeout: 90
testSuiteStep: 90

Global timeout, testSuite timeout, and testSuite timeout are set to 90 minutes.   The target platform is set to Windows. Please set the [runson] key to [mac] if the tests have to be executed on the macOS platform.

runson: win

Playwright-JS js files in the 'Tests' folder contain the Test Scenario run on the HyperExecute grid. In the example, the Test file tests/test_4.spec.js run in parallel on the basis of scenario by using the specified input combinations.

matrix:
  os: [linux]
  methods: ['tests/test_4.spec.js:4','tests/test_3.spec.js:4','tests/test_2.spec.js:4','tests/test_1.spec.js:4']

The testSuites object contains a list of commands (that can be presented in an array). In the current YAML file, commands for executing the tests are put in an array (with a '-' preceding each item). The npx command is used to run tests in .js files. The tags are mentioned as an array to the methods key that is a part of the matrix.

testSuites:
  - npx playwright test $methods

Pre Steps and Dependency Caching

Dependency caching is enabled in the YAML file to ensure that the package dependencies are not downloaded in subsequent runs. The first step is to set the Key used to cache directories.

cacheKey: '{{ checksum "package-lock.json" }}'

Set the array of files & directories to be cached. In the example, all the packages will be cached in the CacheDir directory.

cacheDirectories:
  - node_modules

Steps (or commands) that must run before the test execution are listed in the pre run step. In the example, the packages listed in requirements.txt are installed using the npm install command.

pre:
  - npm install

Artifacts Management

The mergeArtifacts directive (which is by default false) is set to true for merging the artifacts and combing artifacts generated under each task.

The uploadArtefacts directive informs HyperExecute to upload artifacts [files, reports, etc.] generated after task completion. In the example, path consists of a regex for parsing the directory (i.e. reports that contains the test reports).

mergeArtifacts: true

uploadArtefacts:
  [{
    "name": "Reports",
    "path": ["Reports\\"]
  }]

HyperExecute also facilitates the provision to download the artifacts on your local machine. To download the artifacts, click on Artifacts button corresponding to the associated TestID.

Test Execution

The CLI option --config is used for providing the custom HyperExecute YAML file (i.e. yaml/win/.hyperexecute_matrix.yaml). Run the following command on the terminal to trigger the tests in Test file Scenario on the HyperExecute grid.

./hyperexecute --config --verbose yaml/win/.hyperexecute_matrix.yaml

Visit HyperExecute Automation Dashboard to check the status of execution:

Run Playwright-JS tests on Windows and Linux platforms

The CLI option --config is used for providing the custom HyperExecute YAML file (i.e. yaml/win/.hyperexecute_autosplits.yaml for Windows and yaml/linux/.hyperexecute_autosplits.yaml for Linux).

Run the following command on the terminal to trigger tests on Windows platform:

./hyperexecute --config --verbose yaml/win/.hyperexecute_autosplits.yaml

Run the following command on the terminal to trigger tests on Linux platform:

./hyperexecute --config --verbose yaml/win/.hyperexecute_autosplits.yaml

Secrets Management

In case you want to use any secret keys in the YAML file, the same can be set by clicking on the Secrets button the dashboard.

All you need to do is create an environment variable that uses the secret key:

env:
  AccessKey: ${{.secrets.AccessKey}}

Navigation in Automation Dashboard

HyperExecute lets you navigate from/to Test Logs in Automation Dashboard from/to HyperExecute Logs. You also get relevant get relevant Playwright test details like video, network log, commands, Exceptions & more in the Dashboard. Effortlessly navigate from the automation dashboard to HyperExecute logs (and vice-versa) to get more details of the test execution.

We are here to help you :)
