Running tests with cypress.
For details on why we picked Cypress, check the following PR
Check the Cypress docs for more information
How to run it
- To run the test cases headless run:
yarn test - To debug the tests you can use cypress interactive UI by running
yarn cypress open(You will need to have the UI running in a separate terminalyarn start)
How to write a new test case
Any new test cases should be added under the cypress/integration folder. Aim to group similar test cases in one file.
If any stub/mock is needed, those should be added to cypress/fixtures folder. Cypress has a built in way of using those.
We use data-testid as a practice to define selectors in the code and we leverage the Cypress Testing Library plugin to find the elements in the tests.
- We leverage a
data-testidor selecting by text (findAllByText,findByText) to make sure the test cases are decoupled from the implementation.
We leverage the Page Object Pattern to abstract away selectors and actions and simplify changes required to future refactors. Take a look to any example under the cypress/pageObject folder to see how that pattern is implemented.
Finally any common functionality such as for example login should be abstracted into a command. CY Commands can be added into the cypress/support folder. Feel free to group similar commands into files (You only need to make sure those get imported into the cypress/support/index.ts file)
Happy testing!!!
snapshot testing
We use cypress-image-snapshot for snapshot testing (yarn run test:snapshots). This is a relatively cheap way of identifying changes based on page screenshots.
When a test that contains a matchImageSnapshot call is run, it compares the snapshot to the corresponding one in the snapshots directory. If Any change is detected, the test will fail, and the diff can be found in the snapshots/*/__diff_output__ folder. If the change is intentional, we should "accept" those changes by updating the snapshot and include it in the commit. To update the snapshots run yarn run test:snapshots:update
Is is not yet included in CI because there is an existing issue where colors differ depending on the host machine running the tests.
