fixture-compare

fixture-compare

Compare test fixtures with each other, with strings, and against the results of transforms.

v1.1.0

Compare a String to a Fixture

import {inputMatchesFile} from 'fixture-compare';
const input = 'some string';
const fixture = 'result.txt'
inputMatchesFile(input, fixture);

Run a Fixture Through a Transform

Loads a fixture, runs it through a transform, then compares the results to a fixture with the same name, appended with .output.

import fixtureCompare from 'fixture-compare';
const fixture = 'test-1';
const transform = (text) => text.split('').reverse();
fixtureCompare(fixture, transform);

Run a Fixture Through a Transform, Specify Result Fixture

Same as the previous example, but allows you to specify a different output file.

import fixtureCompare from 'fixture-compare';
const input = 'test-2';
const output = 'test-2.result';
const transform = (text) => text.split('').reverse();
fixtureCompare(input, transform, output);

Specify Fixtures Directory

By default, paths to fixtures are assumed to be relative to {cwd}/test/fixtures. To specify another directory...

import {setFixturesDir} from 'fixture-compare';
setFixturesDir(path.join(__dirname, 'somewhere/else'));

Log Differences

To log differences when fixtures do not match, use setLogging.

import {setLogging} from 'fixture-compare';
setLogging(true);
