ts file have all its tests grouped in describe block like this: describe('SomeComponent', () => {...} You can easily run just this single block, by prefixing the describe function name with f : fdescribe('SomeComponent', () => {...}
You can use fit() or fdescribe() instead of it() and describe() to achieve what is known as focussed test cases. describe("test spec", function() { it("test case 1", function() { }); fit("test case 2", function() { }); }); In the above example, only test case 2 would get executed.
Karma. Karma is a test runner for JavaScript. Along with Jasmine, Karma is one of the default testing tools for Angular.
Each of your .spec.ts
file have all its tests grouped in describe
block like this:
describe('SomeComponent', () => {...}
You can easily run just this single block, by prefixing the describe
function name with f
:
fdescribe('SomeComponent', () => {...}
If you have such function, no other describe
blocks will run.
Btw. you can do similar thing with it
=> fit
and there is also a "blacklist" version - x
. So:
fdescribe
and fit
causes only functions marked this way to runxdescribe
and xit
causes all but functions marked this way to runConfigure test.ts
file inside src
folder:
const context = require.context('./', true, /\.spec\.ts$/);
Replace /\.spec\.ts$/
with the file name you want to test. For example: /app.component\.spec\.ts$/
This will run test only for app.component.spec.ts
.
You can test only specific file with the Angular CLI (the ng
command) like this:
ng test --main ./path/to/test.ts
Further docs are at https://angular.io/cli/test
Note that while this works for standalone library files, it will not work for angular components/services/etc. This is because angular files have dependencies on other files (namely src/test.ts
in Angular 7). Sadly the --main
flag doesn't take multiple arguments.
This worked for me in every case:
ng test --include='**/dealer.service.spec.ts'
However, I usually got "TypeError: Cannot read property 'ngModule' of null" for this:
ng test --main src/app/services/dealer.service.spec.ts
Version of @angular/cli 10.0.4
--include
it's work with --include
ng test --include src/app/path-to-component/path-component.component.spec.ts
I tried --main
but it shows all fail results while it's not. I think --main
will change the main test.ts
file.
