Creating JavaScript Unit Tests
IntelliJ IDEA provides integration with JavaScript unit testing frameworks thus providing rich coding assistance for writing JavaScript unit tests. To get framework-aware coding assistance, download the desired framework, configure it as a IntelliJ IDEA JavaScript library, and define its visibility and scope.
The visibility status of a library determines whether it can be used in one project (Project) or can be re-used at the IDE level (Global).
The scope of a library defines the set of files and folders in which the library is considered as library, that is, it is write-protected, excluded from check for errors and refactoring, but only affects the completion list and highlighting.
For details, see Configuring JavaScript Libraries.
To create JavaScript unit tests, perform these general steps
-
Create a folder
testat the same level as thesrcfolder. -
Populate the
testfolder. For each production file, create a separate test file and name it as follows:<name of production file>.<Test>.js. - Mark the folder where the tests are stored as a test source folder, see Configuring Content Roots.
- If necessary, have IntelliJ IDEA detect and enable the required testing framework on-the-fly.
