test
Is this a regression?
The previous version in which this bug was not present was
22.0.9
Description
My app is still using karma to run tests. On angular and cli 22.0.8/22.0.9 the unit tests run fine. I updated to 22.1.0 and the unit tests fail to compile saying that the spec.ts files cannot be found during compilation.
I created a new angular project using ng 22.1.0 and the karma test runner and see the same error.
Minimal Reproduction
-
angular/cli 22.1.0 is installed globally: ng --version prints out 22.1.0. I am using node 26.5.1.
-
Run ng new foo --test-runner=karma to create a new project.
-
In the foo folder run npm test. The test fails to build. See error below.
