Internally this method is called inside [`vitest.start`](/advanced/api/vitest#start), [`vitest.init`](/advanced/api/vitest#init) or [`vitest.mergeReports`](/advanced/api/vitest#mergereports). If you are using programmatic API, make sure to call either one dependning on your needs before calling [`vitest.runTestSpecifications`](/advanced/api/vitest#runtestspecifications), for example. Built-in CLI will always run methods in correct order.

Note that you can also get access to `vitest` instance from test cases, suites and test modules via a [`project`](/advanced/api/test-project) property, but it might also be useful to store a reference to `vitest` in this method.

- `passed`: test run was finished normally and there are no errors
141

- `failed`: test run has at least one error (due to a syntax error during collection or an actual error during test execution)
142
-
- `interrupted`: test was interruped by [`vitest.cancelCurrentRun`](/advanced/api/vitest#cancelcurrentrun) call or `Ctrl+C` was pressed in the terminal (note that it's still possible to have failed tests in this case)

If Vitest didn't find any test files to run, this event will be invoked with empty arrays of modules and errors, and the state will depend on the value of [`config.passWithNoTests`](/config/#passwithnotests).

If you intend to keep the `Vitest` instance, make sure to at least call [`init`](/advanced/api/vitest#init). This will initialise reporters and the coverage provider, but won't run any tests. It is also recommended to enable the `watch` mode even if you don't intend to use the Vitest watcher, but want to keep the instance running. Vitest relies on this flag for some of its features to work correctly in a continous process.

The ability to run tests in headless mode is not affected by this. You can still run all instances in parallel as long as they don't have `headless: false`.
