How to programmatically skip a test in mocha?

Question

I have a code where certain tests will always fail in CI environment. I would like to disable them based on an environment condition.

How to programmatically skip a

Answer 1

Say I wanted to skip my parametrized test if my test description contained the string "foo", I would do this:

// Skip parametrized test if description contains the string "foo"
(test.description.indexOf("foo") === -1 ? it : it.skip)("should test something", function (done) {
    // Code here
});

// Parametrized tests
describe("testFoo", function () {
        test({
            description: "foo" // This will skip
        });
        test({
            description: "bar" // This will be tested
        });
});

In your case, I believe that if you wanted to check environment variables, you could use NodeJS's:

process.env.ENV_VARIABLE

For example (Warning: I haven't tested this bit of code!), maybe something like this:

(process.env.NODE_ENV.indexOf("prod") === -1 ? it : it.skip)("should...", function(done) {
    // Code here
});

Where you can set ENV_VARIABLE to be whatever you are keying off of, and using that value, skip or run the test. (FYI the documentation for the NodeJS' process.env is here: https://nodejs.org/api/process.html#process_process_env)

I won't take complete credit for the first part of this solution, I found and tested the answer and it worked perfectly to skip tests based on a simple condition through this resource: https://github.com/mochajs/mocha/issues/591

Hope this helps! :)
