Streams test library
streamtest
is a set of utils to test your stream based modules simply.
In fact, this repository's tests is a perfect example of its own usage ;).
First install streamtest
in your project:
npm install --save-dev streamtest
Then, use it:
import StreamTest from 'streamtest';
describe('My Stream Lib', () => {
// here goes your code
it('should work', async (done) => {
const [outputStream, resultPromise] = StreamTest.toText();
StreamTest.fromChunks(['a ', 'chunk', 'and', 'another'])
.pipe(myTestedStream)
.pipe(outputStream);
assert.equal(await resultPromise, 'the text as i should be')
});
});
Feel free to submit us your improvements. To do so, you must accept to publish your code under the MIT license.
To start contributing, first run the following to setup the development environment:
