Custom Location is not working as expected for --config

[AartiJ]

Prerequisites

• Checked that your issue hasn't already been filed by cross-referencing issues with the faq label
• Checked next-gen ES issues and syntax problems by using the same environment and/or transpiler configuration without Mocha to ensure it isn't just a feature that actually isn't supported in the environment in question or a bug in your code.
• 'Smoke tested' the code to be tested by running it outside the real test suite to get a better sense of whether the problem is in the code under test, your usage of Mocha, or Mocha itself
• Ensured that there is no discrepancy between the locally and globally installed versions of Mocha. You can find them with: node node_modules/.bin/mocha --version(Local) and mocha --version(Global). We recommend that you not install Mocha globally.

Additional Information

[AartiJ]

my .mocharc.js configuration file is in another node artifact which I am basically using in this e2e project.

[juergba]

Is the path node_modules/../lib/.mocharc.js correct? Try to use an absolute one instead.

[AartiJ]

yes, the path is correct and was using absolute path. I have updated the description above.

[juergba]

Is node_modules/../lib/.mocharc.js not identical with lib/.mocharc.js ?

I'm quite sure (I don't know macOS) that node_modules/ace-api-testlib/lib/.mocharc.js is not an absolute path. If your path is a relative one, try: ./node_modules/ace-api-testlib/lib/.mocharc.js

[AartiJ]

tried your suggestion and still getting the same issue.

mocha --no-opts --config ./node_modules/ace-api-testlib/lib/.mocharc.js --reporter mocha-allure-reporter

Adding "./" to the beginning will have no effect (doesn't hurt or help).

Run this from same location as your command above.

$ pwd
$ ls -al node_modules/ace-api-testlib/lib/.mocharc.js

Relatively certain the ls command will fail though...

List the possibilities...

$ find node_modules -name ".mocharc*"

[plroebuck]

yes, the path is correct and was using absolute path. I have updated the description above.

The path above is relative. Absolute paths on UN*X begin with a slash character '/' (i.e., the path from the root directory).

[AartiJ]

@plroebuck I got the below output for the commands you requested to execute
C02Q383EG8WP:ace-ilp-lib ajadeja$ ls -al node_modules/ace-api-testlib/lib/.mocharc.js
-rw-r--r-- 1 ajadeja 1849915958 530 Mar 7 16:31 node_modules/ace-api-testlib/lib/.mocharc.js
C02Q383EG8WP:ace-ilp-lib ajadeja$ find node_modules -name ".mocharc*"
node_modules/ace-api-testlib/lib/.mocharc.js

[plroebuck]

you left out the most important -- pwd

[AartiJ]

@plroebuck Sorry here it is
C02Q383EG8WP:ace-ilp-lib ajadeja$ pwd
/Users/ajadeja/git_test/ace-ilp-lib
C02Q383EG8WP:ace-ilp-lib ajadeja$ ls -al node_modules/ace-api-testlib/lib/.mocharc.js

node_modules/ace-api-testlib/lib/.mocharc.js
C02Q383EG8WP:ace-ilp-lib ajadeja$

Just FYI: I have my project open in Webstorm, and I am running an npm command from Webstorm Project Terminal

[plroebuck]

$ which mocha

Quick test with absolute path...

$ npm test
