Protractor

Protractor is a test framework for Angular and AngularJS applications. Protractor executes tests against your application running in a real browser, which ensures correctness and trustworthiness of test results. GoLand integrates with Protractor so you can run and debug your tests from inside the IDE. You can see the test results in a treeview and easily navigate to the test source from there.

Before you start

Download and install Node.js.
Debugging of Angular applications is only supported with Node.js version 16 and earlier.
Make sure the JavaScript and TypeScript plugin is enabled in the settings. Press Control+Alt+S to open the IDE settings and then select Plugins. Click the Installed tab. In the search field, type JavaScript and TypeScript. For more details about plugins, see Managing plugins.
Install and enable the Angular and AngularJS plugin on the Settings | Plugins page, tab Marketplace, as described in Installing plugins from JetBrains Marketplace.

Install Protractor

You can install Protractor locally, in your project, or globally. Global installation is preferable.

Install Protractor globally

In the embedded Terminal (Alt+F12) , type:
npm install -g protractor
To download the necessary binaries, type webdriver-manager update. See also Getting Started on the Protractor official website.

Run tests

Protractor tests are launched only through a run/debug configuration.

Create a Protractor run configuration

Open the Run/Debug Configuration dialog (Run | Edit Configurations on the main menu), click in the left-hand pane, and select Protractor from the list. The Run/Debug Configuration: Protractor dialog opens.
Alternatively, select a test file in the Project tool window and select Create <filename> from the context menu.
Specify the Node.js interpreter to use.
If you choose the Project alias, GoLand will automatically use the project default interpreter from the Node interpreter field . In most cases, GoLand detects the project default interpreter and fills in the field itself.
You can also choose another configured local interpreter or click and configure a new one.
Specify the location of the protractor package and the path to the protractor.conf.js configuration file. If you followed the standard installation, GoLand detects all these paths and displays them in the corresponding fields.
Specify the tests to run. This can be a specific test or suite, an entire test file, or a folder with test files.

Run tests via a run configuration

Start the Selenium Server manually or configure it to start automatically in protractor.conf.js. For details, see the Protractor official website.
Select the Protractor run/debug configuration from the list of configurations and click in the list or on the toolbar.
View and analyze messages from the server in the <current_run_configuration_name> tab of the Run tool window.

Navigation

With GoLand, you can jump between a file and the related test file or from a test result in the Test Runner Tab to the test.

To jump between a test and its subject or vice versa, open the file in the editor and select Go to | Test or Go to | Test Subject from the context menu, or just press Control+Shift+T.
To jump from a test result to the test definition, click the test name in the Test Runner tab twice, or select Jump to Source from the context menu, or just press F4. The test file opens in the editor with the cursor placed at the test definition.

Debug tests

A debugging session for Protractor tests is started only through a run/debug configuration.

To start debugging tests

Create a Protractor run/debug configuration as described above.
Select the Protractor run/debug configuration from the list of configurations and click in the list or on the toolbar.
In the Debug tool window that opens, proceed as usual: step through the tests, stop and resume test execution, examine the test when suspended, run JavaScript code snippets in the Console, and so on.
