Some simple first async tests for the AngularJS IndexedDB wrapper I'm hacking on. Using Karma, Mocha and Chai.Somewhat painful but it it seems to be working rather well.

indexeddb.spec.js

describe('IndexedDB', function() {
  var provider;

  beforeEach(function(done) {
    module('cmlenz.indexedDB', function(indexedDBProvider) {
      provider = indexedDBProvider;
      provider.connect("angular-indexeddb-tests", 1, function(evt, db) {
        db.createObjectStore('test', {keyPath: 'key'});
      });
    });
    // Need to call inject to make sure the database setup above is actually
    // performed before test setup is done
    inject(function(indexedDB) {
      indexedDB.transaction('test', function(test) {
      }).then(function() {
        done();
      });
    });
  });

  it('provider should exist', function(done) {
    inject(function(indexedDB) {
      expect(provider).to.exist;
      expect(indexedDB).to.exist;
      done();
    });
  });

  it('should insert a new object', function(done) {
    inject(function($q, indexedDB) {
      indexedDB.transaction('test', 'readwrite', function(test) {
        test.add({key: 42, value: "foo"}).then(function() {
          $q.all([
            test.count().then(function(num) { expect(num).to.equal(1); }),
            test.get(42).then(function(obj) { expect(obj.value).to.equal("foo"); })
          ]).then(function() {
            done();
          })
        });
      });
    });
  });

  it('should update an existing object', function(done) {
    inject(function($q, indexedDB) {
      indexedDB.transaction('test', 'readwrite', function(test) {
        test.add({key: 42, value: "foo"}).then(function() {
          test.put({key: 42, value: "bar"}).then(function() {
            $q.all([
              test.count().then(function(num) { expect(num).to.equal(1); }),
              test.get(42).then(function(obj) { expect(obj.value).to.equal("bar"); })
            ]).then(function() {
              done();
            })
          });
        });
      });
    });
  });

  afterEach(function(done) {
    inject(function($rootScope, indexedDB) {
      $rootScope.$apply(function() {
        indexedDB.delete().then(function() {
          done();
        });
      });
    });
  });

});
