March 5, 2025Error with Angular unit testing after placing routerLink in my template
The error you're encountering is likely due to the fact that the RouterLink directive is not being properly initialized in your unit tests. The RouterLink directive expects certain dependencies to be provided, such as the Router service and the ActivatedRoute service. To fix this issue, you need to properly configure the RouterTestingModule in your unit tests and provide the necessary dependencies for the RouterLink directive. More on reddit.com

May 15, 2024Do I need Unit testing if I use Cypress?
They have different purposes. Unit tests: Does my component / helper / etc still work? Integration test: Does this feature / UI still work? E2E: Does this important user flow still work? Current best practices, so far as I understand it, is mostly unit and integration testing (how much of each is up to debate) since they're the easiest to set up and run the fastest which makes them the fastest feedback loop that everything is good (or not good). E2E tests are mostly for things that really matter, like login and purchase flows, friending on social platforms, stuff like that. All your tests should be verifying that when a change is made the functionality of your website does not change unintentionally. More on reddit.com
