testsome

testsome is a small JavaScript test runner without any dependencies.

Usage

To run a test with testsome, a test function is provided. It takes the test's name and a function which will be called:

function test(name: string, func: (t: T) => void): void

The passed function func gets a parameter of type T which can be used to manage test state:

interface T {
    skip(): void;
    fail(): void;
    error(msg?: string): void;
    fatal(msg?: string): void;
    run(name: string, func: TestFunc): boolean;
}

T.skip()

The skip method marks the test as skipped and stops its execution.

T.fail()

The fail method marks the test as failed and continues it execution.

T.error(msg)

The error method reports an optional error message and marks the test as failed. If no msg parameter is provided, this function will be equivalent to calling fail.

T.fatal(msg)

The fatal method reports an optional error message and stops the test execution. This function is equivalent to calling error followed by returning from the test function.

T.run(name, func)

The run method start a subtest with the provided name. It basically has the same semantics as the test function. The return value reports whether the subtest succeeded or not.

Command Line

testsome [options] [file ...]

Run all tests which are defined in the provided files. A file could also be a glob pattern,
which includes every file the pattern matches.

Options:
    --run regexp
        Run only the test where the name matches the regular expression. All other will be ignored.
        The regular expression is split into parts by unbracketed slashes where each part must match
        the corresponding subtest. All parents of a matching test are run, too. For example, for
        '--run A/B' runs the test A with its subtests matching B.

Example

test.js

import {test} from "testsome";

test("my first test", t => {
    if(!initializeTest()) {
        t.fatal("cannot initialize test");
    }

    t.run("subtest", t => {
        if(somethingIsWrong) {
            t.error("something went wrong");
        }
    });
});
