Run single test of a specific test suite in Jest

Question

I have a file called "test-file-1", within it i have a few describes (test suites) with unique names and inside them i have tests which may have similar names across test suites.

To run a single test suite or test i type the command below.

npm test -- -t "Test Suite or Test"

I'm trying to figure out how to run a single test of a specific test suite.

So did you read the CLI docs? https://jestjs.io/docs/en/cli.html — jonrsharpe, Jul 15 '19 at 18:42

Give the path of the file you want to test :

npm test path/of/your/testfile.js -t "test name"

will run only the test (or group) named "test name" of this specific file.

that's the problem, i have a file with multiple tests with the same or similar name, the only thing that differs them is the test suite. – Gabriel Souza Jul 16 '19 at 11:59

easily get the path of the file in VSC. Right click the file and select "Copy Relative Path". – Fer Toasted Aug 17 '22 at 21:16

After trying a lot of different things i found out that it was simpler than i thought.

You simply have to put the test after the test suite in the same string:

npm test -- -t "<Test Suite> <Test>"

import LoggerService from '../LoggerService ';

describe('Method called****', () => {
  it('00000000', () => {
    const logEvent = jest.spyOn(LoggerService , 'logEvent');
    expect(logEvent).toBeDefined();
  });
});

run below command npm test -- tests/LoggerService.test.ts -t '00000000'

Point to the test suite in jest config file via "testMatch":["**/path/testSuite/*.js"]

and now execute by giving unique testname by jest testName

Here you have to update the testMatch every time which is your testSuite

i'm looking for a simpler way, manually changing every time is not practical. – Gabriel Souza Jul 16 '19 at 20:39
your testsuite is dynamic and testcase is static so you have to change the testsuite all the time then why dont you run using `jest -t /path/to/testSuite/testcase.js` . Everytime you have to only pass testsuite here and remove testMatch from config file – Chandra Shekhar Jul 17 '19 at 05:18

If you are using a jest config file, you can use the testNamePattern key to configure this. So your config file could look something like

jest-e2e.json

{
  "moduleFileExtensions": ["js", "json", "ts"],
  "rootDir": ".",
  "testEnvironment": "node",
  "testRegex": ".spec.ts$",
  "testNamePattern": "login",
  "transform": {
    "^.+\\.(t|j)s$": "ts-jest"
  },
  "bail": true,
  "verbose": true,
  "testTimeout": 30000
}

This will only run test that has "login" in one of the test pattern

Reference: https://jestjs.io/docs/cli#--testnamepatternregex

For me, it only works with:

npm run test -- tests/01_login.js --testcase "Should login into Dashboard"

npm run <script> -- <test suite path> --testcase "<test case>"

my script in package.json:

"test": "env-cmd -f ./.env nightwatch --retries 2 --env selenium.chrome",

at nightwatch version 1.3.4

in latest versions of jest you could use it.only(), describe.only(), etc in which case it will just execute that single test without having to pass a file or filter parameter
