this is my config file , all the tests are running well but coverage folder is not getting generated p why?

Does this really work, 'wwwroot/app/**/!(*.spec).ts': ["karma-typescript"]? All ".spec.ts" files are excluded from instrumentation by default (see karmaTypescriptConfig.coverageOptions.exclude) so you shouldn't need to exclude them. Does the coverage folder get generated if you include also the spec files in the preprocessor setting, ie 'wwwroot/app/**/*.ts': ["karma-typescript"]?

[asif-khan17]

No.. After changing preprocessor settings to 'wwwroot/app/*/.ts': ["karma-typescript"] .. it still not generates coverage folder

[erikbarke]

Ok, you're also adding all of your project files with included: false which means you have to load them manually in the browser with Require.js or similar, is that what "karma-test-shim.js" does? It looks like you're mixing frameworks here, which I'm guessing you really don't need since karma-typescript uses CommonJS internally and does all the bundling and module loading automatically for you.
