Jest with special tests run on occasion

Question

How do I write Jest tests that only runs when specifically invoked on the command line?

I want to have integration-like tests that interact with online services from Google and Amazon in a React project.

If I create a differently named test file src/google.itest.js:

• Good: It is not normally run by jest
• Good: It resides where all other tests are
• Bad: jest cannot be made to run it:

jest --testPathPattern="\.itest"
Jest still does not run the tests, probably because it is blocked by the testMatch configuration option: testMatch:

**/__tests__/**/*.js?(x),**/?(*.)(spec|test).js?(x)

How do I write Jest tests that only runs when specifically invoked on the command line?

Answer 1

It works with RegExp (presumably those are ECMAScript regexps):

jest --testRegex 'src/.*itest.*'

Note that an equal sign separating the long option and its value is not required
