How to execute only one test spec with angular-cli

⚡️How to Execute Only One Test Spec with Angular-CLI⚡️

Hey there tech enthusiasts! 🖐️ Today, we're going to tackle a common issue that many Angular developers face: running tests against only one selected spec file using Angular-CLI. 🚀

Imagine this scenario: you have a big Angular project built with Angular-CLI (beta 20), and you only want to run tests for a specific spec file. 🤔 How can you accomplish that? Let's dive into the solutions! 💡

✅ Solution 1: Using the --include flag

Angular-CLI provides an easy solution to run tests against a specific spec file by using the --include flag. 🎯

Here's an example of how you can use it:

ng test --include=path/to/your/spec/file.spec.ts

By specifying the --include flag, Angular-CLI will only run the tests within the specified spec file. 🙌

✅ Solution 2: Modifying the karma.conf.js file

If you prefer a more permanent solution and want to limit karma tests to specific files, you can modify the karma.conf.js file.

1. Open the karma.conf.js file located in the root of your Angular project.

2. Locate the files property, which contains an array of file patterns to include and exclude during testing.

3. Add the path to your desired spec files using the pattern option, like this:

files: [
  // Other files and patterns...
  { pattern: 'path/to/your/spec/file.spec.ts', watched: true },
  // Other files and patterns...
]

By modifying the files property, you can limit the tests to only the specified spec files. Stay focused! 🔬

👉 Remember to revert any changes made to the karma.conf.js file after you're done running your targeted tests. Otherwise, you might encounter unexpected behavior during future test runs.

💥 Conclusion and Call-to-Action

You now have two handy solutions to execute only one test spec with Angular-CLI. Whether you prefer the flexibility of the --include flag or the permanence of modifying the karma.conf.js file, you can easily accommodate your testing needs. 💪
