每次保存更改时，如何停止Selenium Standalone Server运行Mocha / Chai / WebdriverIO测试？

Question

I am currently using a testing framework with Mocha, Chai, and WebdriverIO. As it stands, the Selenium Standalone Server runs the full test suite whenever I save a change to the spec file. I want to disable this and only run the test suite when I enter the command to do so in the terminal. This command currently works, but because the tests are also being run automatically on save, sometimes multiple identical tests run concurrently, causing errors.

How do I stop the Selenium Standalone Server from auto-running tests?

Update: As a commenter requested, here is my package.json :

Answer 1

When npm start is run, it runs the following command:

npm-run-all --parallel test:watch open:src lint:watch

The test:watch is what is likely triggering your test suite to run again.

If you want to avoid that, just run npm run open:src to start your server, then npm test to run your test.
