Testing

The WebAssembly Studio mostly relies on unit tests to verify the functionality. The architecture (react + flux) was chosen just for this reason. We are using the jest as our testing platform.

Execution

The tests are executed by running npm run test command. That includes execution of:

• tslint for TypeScript coding guidelines verification;
• jest for unit tests.

It's possible to run just the unit tests using jest command. Running it via the jest command allows, e.g. to specify the particular test, update the snapshot, etc.

Creation of a unit test

The unit tests are location at the "tests/" folder and further grouped by particular component or action. To verify the components state we are using enzyme testing utilities.

The jest allows to replace modules with mocks -- that will allow to simply unit test creation.

Note: The project is at its first iterations and is migrated from the pilot code. It is essential to add (unit) test to existing code first.
