I was trying to update my whole project dependencies, and managed to do it, but when I try to run the tests with ng test --no-watch they don't work, giving me the following error.

It's interesting how it worked perfectly before doing the update, and suddenly it seems like webpack is unable to find the context? Why?

Basically changed most of them to the latest. I even tried to revert and try to update one by one, but as soon as I update angular it breaks, why is so?
Thanks in advance
CodePudding user response：
I had the same issue. For some reason, in our other app doing angular update automatically deleted some code in test.ts, namely:
const context = require.context('./', true, /\.spec\.ts$/);
context.keys().forEach(context);
and the declaration of require above that.
I did that in my other app manually and so far it works. Maybe someone knows the reason for this change.
CodePudding user response：
I had the same issue with a components library after an upgrade from v14 to v15.
Unfortunately pasting the code back from git history did not solve the issue with 0 found test for me.
My solution was to delete the test.ts file in projects/components/src and its reference in the files list in tsconfig.spec.ts. Additionally a patch to the test block in angular.json was needed. Alongside with a extended include pattern list in the tsconfig.spec.ts
angular.json before
{
"builder": "@angular-devkit/build-angular:karma",
"options": {
"main": "projects/components/src/test.ts",
"tsConfig": "projects/components/tsconfig.spec.json",
"karmaConfig": "projects/components/karma.conf.js"
}
}
angular.json after
{
"builder": "@angular-devkit/build-angular:karma",
"options": {
"polyfills": [
"zone.js",
"zone.js/testing"
],
"tsConfig": "projects/components/tsconfig.spec.json",
"karmaConfig": "projects/components/karma.conf.js"
}
}
tsconfig.spec.ts before
{
"files": [
"src/test.ts"
],
"include": [
"**/*.spec.ts",
"**/*.d.ts"
]
}
tsconfig.spec.ts after

"files": [
