cypress-retry

Retry just the failed Cypress.io tests using Cypress module API and AST rewriting

First this script runs all tests in a given spec file. If any tests fail, these tests are returned by the module API. The script parses the spec file source into AST and changes all passing tests from it(...) to it.skip(...), and saves the updated spec file. Then it runs the spec again - and now only the failed tests should run. Then it restores the original spec back to full.

Example

First run - single test has failed

The script has found the failed tests in the spec file

failures: 1
failed test titles:
outside,inside,fails when env variable FAIL is set
found test [ 'outside', 'inside', 'passes' ]
should skip this test
found test [ 'outside', 'inside', 'fails when env variable FAIL is set' ]
found test [ 'outside', 'works from single describe' ]
should skip this test
found test [ 'exists by itself' ]
should skip this test

Once all tests but one test have been switched to it.skip, the tests are retried - this time without env.FAIL=1 variable and the previously failing test is passing. Notice how all other tests are "pending", meaning they have been skipped by the test runner.
