specify is the simplest way i could think to do node.js testing.

It works with sync code and async code all the same.

Please use versions ~0.6.x for node 0.6 and ~1.0.x for node 0.8 or higher.

If you don't like reading and want to see some code you can look at nano's tests and learn there. Also read the specify source code; it's just a couple of lines of code.

var specify = require('specify');

specify('create_by_secret', function (assert) {
  user.create_by_secret({invitation_code: "1234321!!"}, function (err) {
    assert.equal(err.eid, "ec:api:user:create_by_secret:wrong_code");
    assert.equal(err.status_code, 400);
  });
});

specify.run();

The assert calls are callback functions that wrap the assert module. specify figures out how many callbacks you are calling by static-analysis. To put it simply, it counts the number of times you wrote assert. When that number of assertions is met, or when a timeout occurs, that test is complete and we can execute the next one.

Static analysis does not work for a for loop and some other flow control constructs. In that case you can use assert.expect(nr) to tell specify how many assertions to expect:

specify('more_assertions_than_asserts', function(assert) {
  assert.expect(5);
  for(var i in [1,2,3,4,5]) {
    assert.equal(i,i);
  }
});

specify runs tests one by one, not in parallel. If you set assert.expect higher than the number of assert function calls the execution will stop, and your current test will never finish. You can circumvent this by setting a timeout:

specify('foo', 50, function (assert) {
  call_to_db_that_takes_a_long_time(function (data) {
    assert.equal(data, 'foo');
  });
});

Because tests are serialized, specify can catch uncaught exceptions and continue to run. You will get a report about the error that was thrown somewhere in your stack. This is analogous to the functionality the community refers to as domains.

specify is standalone; you don't need any special binaries to run it.

If you think all these specify functions make your code look bloated, you can also run a single function:

var specify = require('specify')
  , request = require('request')
  ;

specify.run(

  function (assert) {

    var get = { uri: "http://someservice.com/1/apps/dscape", json: true }
      , del = { uri: "http://someservice.com/1/apps/dscape", method: "DELETE"
              , json : true }
      , app_name
      ;

    request(get, function (err, _, body) {

      assert.equal(err,null);
      assert.ok(body.rows);
      assert.ok(body.total_rows >= 1);
      assert.ok(body.rows.length >= 1);

      app_name = body.rows[0].value.app_name;
      del.uri += "/" + app_name;

      request(del, function (err, resp, body) {

        assert.equal(err,null);
        assert.equal(resp.statusCode, 200);
        assert.equal(body.app.name, app_name);
        assert.equal(body.app.user,"dscape");

      });

    });

  }

);

1. install npm
2. npm install specify
3. var specify = require('specify');

In specify you specify which tests you want to run:

var specify = require('specify')
  , filters = process.argv.slice(2)
  ;

specify('foo', function (assert) {
  assert.equal('foo', 'foo');
});

specify('bar', function (assert) {
  assert.equal('bar', 'baz', 'bar failed');
});

specify('baz', function (assert) {
  assert.equal('baz', 'baz');
});

specify.run(filters);

If you feel like the output sent to stdout is ugly, you can write your own reporter and send in a pull request.

Now use it:

specify('specify#ask_for_a_specific_reporter', function(assert) {
  specify.reporter('my_awesome_reporter');
  setTimeout(function (){
    assert.ok(true);
  },1);
});

You can also do this with a function if you like:

specify('specify#custom_reporter_from_function', function(assert) {
  specify.reporter(function (name, report, errors) {
    console.log(name);
  });
  setTimeout(function () {
    assert.ok(false, 'i see dead people');
    assert.ok(true);
  },1);
});

Samples are available in the /test folder.
