TL;DR: Look for files where the error messages might have been saved to. There may be hints in console output.

It is up to the apps called by NPM to print the needed information. In other words: you probably should change your build code (probably your package.json) to display the log you need. Often, it is not practical or even viable, but that's the general approach.

OTOH, sometimes the information is being sent to a different place. For example, consider the line below, taken from the output in the question and broken into lines for more legibility:

Dunno if GitHub action is same like Jenkins. But on Jenkins you need to run test with --browsers=ChromeHeadless. And the error looks like that GitHub is trying to open Chrome.

So try to change your test:ci in package.json

When I run ng test --code-coverage, and then run sonar-scanner, still not able to see coverage report on sonar server.

ANSWER

Answered 2022-Mar-07 at 19:13

SonarQube has replaced supporting typescript keyword with javascript, since last few versions. Use sonar.javascript.lcov.reportPaths for configuring report path instead of sonar.typescript.lcov.reportPaths in your sonar.properties file.
As per my knowledge, as of now SonarQube is only supporting coverage integration using lcov.info file. Make sure your karma configuration is generating lcov.info file at configured path.
For generating lcov format coverage report, you may follow below steps:

Using karma-coverage: (Recommended)
- Make sure (in package.json) you have karma-coverage installed. Generally it is pre-installed with new angular project.
- Update your karma.conf.js file as below:
  - Add { type: 'lcov', subdir: 'lcov-report' } under karma-coverage reporters.
- Make sure that you don't have any duplicate configuration.
- Remove any other coverage reporter and its configuration to avoid conflict.
- Ideally, your karma.config.js should look like below:

ANSWER

Answered 2022-Feb-13 at 17:20

I wrapped the get method on the web object in a function and finally I got it right by creating the mock below. My wrapper is using a .then pattern which is the reason for the double promise resolve in the mock.

IMPORTANT the mock can't be inside a it/test or describe, it must be on the top level as also stated in the docs

I also mocked the sp.setup function in the same mock as that was throwing an error otherwise. Accordingly - you need to set up a double as per my finding. I have tried ts-sinon/ts-mockito etc but nothing took me all the way.

How can I get coverage maps using current ts-jest?

Asked 2021-Dec-28 at 14:12

Similar to Jest, Typescript, ts-jest: Coverage is slightly incorrect - however the answer there applies to older versions of jest where the mapCoverage option existed.

mapCoverage has now been removed and my impression is that ts-jest should now provide coverage reports that work out of the box.

I have followed the ts-jest documentation to install and run ts-jest:
