Running CRA Jest in non-interactive mode

Question

Update: my use case is mainly to run tests at CI, but overriding default CRA Jest parameters is something I\'m generally wondering about.

I\'m run

Answer 1

You should use Jests --watchAll=false flag.

eg:

npm test -- --watchAll=false

Note: this is for react-scripts > 3.00

For older versions:

• react-scripts >= 2.1.4 < 3.00

For non-ci, eg running tests locally, you can pass a --no-watch flag:

npm test --no-watch

• react-scripts <= 2.1.3

CRA looks for a CI environment variable, if its present it doesn't run in watch mode.

CI=true npm test should do what you are looking for
