Tips for executing mocha tests using a reporter

Whenever I execute the command npm test, it displays this output:

 mocha ./tests/ --recursive --reporter mocha-junit-reporter

All the tests are executed successfully. However, when I attempt to run mocha with

./tests/flickr/mytest --reporter junit-reporter
, I encounter this error:

 Unknown "reporter": junit-reporter

How can I properly pass this configuration?

Answer №1

According to the guidelines in the mocha-junit-reporter's documentation:

# add the package to your project
npm install mocha-junit-reporter --save-dev

# execute the test using the specified reporter
mocha test --reporter mocha-junit-reporter --reporter-options mochaFile=./path_to_your/file.xml

Answer №2

I have identified two issues with the command you provided:

mocha ./tests/flickr/mytest --reporter junit-reporter

The first issue is that the mocha command used here is from the global node module. However, when running npm test, it should be targeting the local mocha command within our node_modules folder.

The second issue is that the reporter name should be changed to mocha-junit-reporter instead of junit-reporter

Solution

A workaround is to use the local mocha command like this:

./node_modules/.bin/mocha ./tests/flickr/mytest --reporter mocha-junit-reporter

This is the preferred solution.

Alternatively, you can install mocha-junit-reporter globally with the following commands:

npm install -g mocha-junit-reporter
mocha ./tests/flickr/mytest --reporter mocha-junit-reporter

This method may not be ideal as it could lead to using different versions of mocha and mocha-junit-reporter in the global scope compared to the local node modules.

Cheers
