return n;
}
Return fibonacci(n - 1) + fibonacci(n - 2);
}
test('Test Fibonacci(0)', t => {
t.is(fibonacci(0), 0);
});
test('Test Fibonacci(1)', t => {
t.is(fibonacci(1), 1);
});
//HOOK CALLS
test.before('Before', t => {
console.log('before');
});
test.after('After', t => {
console.log('after');
});
test.beforeEach('BeforeEach', t => {
console.log(' beforeEach');
});
test.afterEach('AfterEach', t => {
console.log(' afterEach');
});
In the above code, we first introduced the AVA module, then created the fibonacci function to be tested, followed by two test cases, and finally four hook methods: before() / after() / beforeEach() / afterEach().
AVA provides a few modification methods to specify the execution method of the test:
1. skip(), skip test cases with skip() added;
2. only(), only execute test cases with only() added;
3. todo(), Placeholder identifier, indicating test cases that need to be added in the future;
4. serial(), executes test cases serially. By default, AVA will execute test cases in parallel.
test('Test Fibonacci(0)', t => {
t.is(fibonacci(0), 0);
});

T in the callback function of the above code is called the assertion execution object, which contains the following methods:
·t.end(), ends the test, only valid in test.cb()
·t.plan(count), specifies the number of executions
·t.pass ([message]), the test passes
·t.fail([message]), the test fails
·t.ok(value, [message]), asserts that the value of value is true Value
·t.notOK(value, [message]), asserts that the value of value is false Value
·t.true(value, [message]), asserts that the value of value is true
·t.false(value, [message]), assert that value is false
·t.is(value, expected, [message]), assert value === expected
·t.not(value, expected, [message]), assert value !== expected
·t.same(value, expected, [message]), assert value and expected The depths are equal
·t.notSame(value, expected, [message]), asserting that value and expected are not equal in depth
·t.throws(function | promise, [error, [message] ]), assert that the function throws an exception or promisereject error
·t.notThrows(function | promise, [message]), assert that the function does not throw an exception or promise resolve
·t.regex( contents, regex, [message]), asserts that contents matches regex
·t.ifError(error, [message]), asserts that error is a false value
Integration testing
Relative to unit testing that focuses on micro-modules, integration testing discovers problems from a macro-overall perspective, so it is also called assembly testing and joint testing. Travis CI is an excellent continuous integration tool that can monitor updates to Github projects and facilitate integration testing of open source software. To use Travis CI, you need to create a .travis.yml configuration file in the root directory of the project (taking Node.js as an example):
language: node_js
node_js:
- "6"
- "5"
before_script:
script:
- npm test
- node benchmark/index.js
after_script:
|
By default, Travis CI will automatically install dependencies and execute the npm test command. You can customize the commands that need to be executed through the script field. Its complete life cycle includes:
·Install apt addons
·before_install
·install
·before_script
·script
·after_success or after_failure
·OPTIONAL before_deploy
·OPTIONAL deploy
·OPTIONAL after_deploy
·after_ script
Benchmark Test Benchmark test uses rigorous test methods, test tools or test systems to evaluate the performance of the target module. It is often used to observe the performance after changes in the software and hardware environment, and the results are reproducible sex. The most commonly used benchmarking tool in the Node.js environment is Benchmark.js, installation method:
npm install --save-dev benchmark
|
Basic example:
const Benchmark = require('benchmark');
const suite = new Benchmark.Suite;
suite.add('RegExp#test', function() {
/o/.test('Hello World!');
})
.add('String#indexOf', function() {
'Hello World!'.indexOf('o') > -1;
})
.on('cycle', function(event) {
console.log(String(event.target));
})
.on('complete', function() {
console.log('Fastest is ' + this.filter('fastest').map('name'));
})
// run async
.run({ 'async': true });
|
Code Coverage The code coverage tool judges the completeness of the module based on the number of lines of code and the number of branches covered by test cases. AVA recommends using nyc to test code coverage, install nyc:
npm install nyc --save-dev
|
Modify .gitignore to ignore related files:
node_modules
coverage
.nyc_output
|
Modify the test field in package.json:
{
"scripts": {
"test": "nyc ava"
}
}
|
Execute npm test and get:
➜ test-in-action (master) ✔ npm test
> test-in-action@1.0.0 test /Users/sean/Desktop/test-in-action
>nyc ava
2 passed
