 ## Testing
 
-TBD
+### Integration tests
+
+Integration testing uses [Cypress](https://www.cypress.io) library, which runs [Gherkin-defined](https://cucumber.io/docs/gherkin) steps.
+
+#### Launching the existing tests
+
+> [!WARNING]  
+> Never run integration tests on production server. Clean-up step would delete all existing entries, e.g. users.
+
+1. Prepare a vagrant server as in `Development Environment`
+2. if you want to launch all the tests in headless mode, execute
+
+```bash
+$ npm run cypress
+```
+
+if you want to open graphical debugger, execute
+
+```bash
+$ npm run cypress:open
+```
+
+and select desired feature file you want to execute.
+
+#### Adding new tests
+
+The integration tests use the **.feature** suffix and can be found in the _tests_ subfolder, together with the steps describing each feature.
+
+### Unit tests
+
+Unit tests use [jest](https://jestjs.io).
+
+#### Launching the existing tests
+
+The existing tests can be launched by executing
+
+```bash
+$ npm run test
+```
+
+#### Adding new tests
+
+The unit tests live, where the component that is being tested lives, the name should be the same, only with the **.test.tsx** suffix instead.
