Eater v3.0.0 Released!!!!!!

eater v3 has the following changes.

• Every test is the isolated process

previous eater, every test files were running in isolated process, but every subtest is not isolated process.
for example,

const test = require('eater/runner').test;

test('abc', (done, fail) => {
  global.mock = 1;
  console.log(global.mock); // 1
  done();
});

test('def', (done, fail) => {
  console.log(global.mock); // 1 because previous test mock is still alive.
  done();
});

after v3.0.0, eater can run every tests in isolated process

const test = require('eater/runner').test;

test('abc', (done, fail) => {
  global.mock = 1;
  console.log(global.mock); // 1
  done();
});

test('def', (done, fail) => {
  console.log(global.mock); // undefined
  done();
});

• No need to use done

before v3.0, we need to use done method to finish the subtest.

const test = require('eater/runner').test;

test('abc', (done, fail) => {
  global.mock = 1;
  console.log(global.mock); // 1
  done();
});

after v3.0, we need not to call done.

const test = require('eater/runner').test;

test('abc', () => {
  global.mock = 1;
  console.log(global.mock); // 1
});

Every subtest process is an isolated.

Reporter improvement

Reporter counts success/failure test count. And show duration time.

Release v3.0.0 RC-0

eater v3.0 will be released soon.

Every subtest process is an isolated.
But currently, we need to make the mode to be stable and improve performance.
so we will pre-release this as v3.0.0-0.

  reportTestName(name) {
  }
  setChildProc(child) {
    child.stdout.on('data', () => {process.stdout.emit('data', '')});
    child.stderr.on('data', () => {process.stderr.emit('data', '')});
  }
  reportFailure(name) {
    console.log('F');
  }
  reportSuccess(name) {
    console.log('.');
  }
}

module.exports = DotReporter;
