Assert testing module for explicit pass/fail console output, with optional AssertionError bypass.
- Props to @SagePadawan for helping me out with this!
npm install batchassert
- Yup, it's available via npm.
batchassert handles the execution of assert tests via deepEqual when provided an array of "test" objects:
let testBatch = [
{ test: <equation>, result: <expected answer>, message: <Message to display on test failure> },
{ test: <equation>, result: <expected answer>, message: <Message to display on test failure> }
];- equation can be any value or function which returns a value.
- result can be any value which equation is expected to equal.
- message (optional) is a string that will be printed if the test fails.
batchassert.testAll(testBatch)
will execute an assert test for every object in the list, in the following manner:
assert.deepStrictEqual(<test>, <result>, <message>)
(or assert.deepStrictEqual(<test>, <result>) if message is left out.)
batchassert will log each test's success or failure to the console, and AssertionErrors will still be thrown by any test that fails. If you prefer to bypass that behavior...
batchassert.testAll(testBatch, false)
... passing false as a second parameter will catch the error, allowing all remaining tests to still execute. The console message for a failed test will print the index of the failed test, as well as the test object's message (if included) or the AssertionError's default message (if not included).
If you leave out a test property in any "test" object then batchassert throws a MissingTestError to let you know that your test was incomplete. Double-check all of the tests in your list and make sure you provide values for all of them.
