Code coverage don't generate report on azure pipeline - azure-devops

Question

my objective:
is to successfully publish my coverage report in a pipeline on azure devops.
To send it to SonarCloud
my successes
locally on my pc
I manage to generate the coverage report in html format and also in xml
1. script task on my pipeline:
- script: |
npx ng test --code-coverage --karma-config src/karma-ci.conf.js
condition: succeededOrFailed()
displayName: Generate unit tests report
2. kama-ci.config.js file:
module.exports = function (config) {
config.set({
frameworks: ['jasmine', '#angular-devkit/build-angular'],
plugins: [
require('karma-jasmine'),
require('karma-chrome-launcher'),
require('karma-junit-reporter'),
require('karma-coverage'),
require('karma-coverage-istanbul-reporter'),
require('#angular-devkit/build-angular/plugins/karma')
],
junitReporter: {
outputDir: 'TestResults/junit',
outputFile: 'unittest-results.xml',
useBrowserName: false
},
coverageReporter: {
type : 'cobertura',
dir : 'TestResults',
subdir: 'coverage',
file: 'code-coverage.xml'
},
reporters: ['progress', 'junit', 'coverage'],
port: 9876,
colors: true,
logLevel: config.LOG_INFO,
autoWatch: false,
customLaunchers: {
ChromeHeadless: {
base: 'Chrome',
flags: [
'--headless',
'--disable-gpu',
'--no-sandbox',
'--remote-debugging-port=9222',
]
}
},
browsers: ['ChromeHeadless'],
singleRun: true
});
};
3. Result error:
But the problem is, report generation always starts and fails in the pipeline.
Here is his result, despite the fact that I give it the condition of always succeeding.

Answer 1

You should add "reporters" inside "coverageReporter" in your karma.config, like so:
coverageReporter: {
type : 'cobertura',
dir : 'TestResults',
subdir: 'coverage',
file: 'code-coverage.xml',
reporters: [ { type: 'cobertura' } ]
},
