Intern: The user guide. Fundamentals. What is Intern? Intern is a complete framework for testing Web sites and applications. Its extensible architecture allows you to write custom test interfaces, executors, and reporters to influence how your tests run & easily integrate with your existing coding environment. Intern also comes with Grunt tasks so it can be quickly added to existing Grunt- based workflows, and is designed to work out- of- the- box with many popular continuous integration services like Jenkins and Travis CI. Intern is used by companies large and small, including some you may have heard of, like Aerohive Networks, Esri, HSBC, IBM, ING, Intuit, Marriott, Mozilla, Stripe, and Twitter. Its built- in support for source maps makes it uniquely well- suited for developers that compile their code to Java. Script from another language, such as Type. Script, or that run tests against production- ready built/minified code. Intern is excellent for teams that are just beginning to write tests; its built- in code coverage analysis makes thorough testing fast and precise, and its functional testing system enables testing of highly procedural code that. It has also been used very successfully by teams that follow a test- driven development approach. Finally, because of its strong architectural patterns, conventions, and expansive feature set, Intern is well- suited for testing extremely large, . If you jump into the middle and feel confused, step back a section or two until you find the information you need to move forward.

Intern provides two strategies for automated testing: unit testing and functional testing. Unit testing works by executing a piece of code directly and inspecting the result. For example, calling a function and then checking that it returns an expected value is a form of unit testing. This is the most common and most useful form of testing for day- to- day development, since it. However, unit tests are limited to only testing certain testable code designs, and can also be limited by the constraints of the execution environment (like browser sandboxes). Functional testing works by issuing commands to a device that mimic actual user interactions. EBooks starting by T - IT eBooks free library.

It’s built around standards like WebDriver and was designed from the ground. Cafe au Lait is the preeminent independent source of Java information on the net.

InformationWeek shares news, analysis and advice on smartphones, tablets, laptops and other mobile devices. Plus, mobile applications and the mobile market. Once an interaction has occurred, these tests verify that the expected information is displayed by the user interface. Because these interactions come from outside the application being tested, they are not restricted by the execution environment. They also allow application code to be treated as a black box, which means functional tests can be written to test pages and applications written in any language. Because functional tests don. Functional tests allow the automation of UI & integration testing that would otherwise need to be performed manually. By understanding & combining both of these testing strategies when testing an application, it becomes possible to effectively automate nearly all of the QA process, enabling much faster development cycles and significantly reducing software defects. Installation. Intern can be installed simply by running npm install intern. Recommended directory structure. While Intern can be used to test code using nearly any directory structure, if you are starting a new project or have the ability to modify the directory structure of your existing project, a few small changes can help make Intern integration a lot easier. The recommended directory structure for a front- end or front+back- end project using Intern looks like this: project. Understanding these fundamental concepts will help you get the most out of testing with Intern. This download includes our core server products and Helix Command Line. The Helix Versioning Engine provided here accommodates up to 5 users and up to 20 workspaces. Code Coverage is a misleading metric if 100% coverage is your goal (instead of 100% testing of all features). You could get a 100% by hitting all the lines once.

Are you are going on a business trip and want to be efficient and maximise the time spent at your. Asynchronous operations. Intern always uses Promise objects whenever an asynchronous operation needs to occur. All suite, test, and reporter functions can return a Promise, which will pause the test system until the Promise resolves (or until a timeout occurs, whichever happens first). Module loader & format. Intern is built on top of a standard AMD loader, which means that its modules are also normally written in the AMD module format. Using an AMD loader instead of something like the built- in Node. Browserify is critical to provide a highly stable and flexible testing system, because AMD is the only stable standard for module loading that has all of these traits: Allows modules to be written for the browser without requiring an intermediate compilation step; Allows modules and other assets to be asynchronously or conditionally resolved by writing simple loader plugins; Allows ! Just write a loader plugin that understands the module format you prefer and you. This allows simple inheritance of parent configurations and enables test configurations to be generated programmatically at runtime. The configuration file is specified using the config argument on the command- line (for Node. URL query- string (for browsers). Take a look at the example configuration file that comes with Intern to learn what a valid configuration looks like. The following configuration options are common to all execution modes in Intern: Option. Type. Defaultbail. If this value is set to true, a failing test will cause all following tests in all suites to be skipped. Path. 3. 0. The common base path for all files that need to be loaded during testing. Node. js)'node. These may include glob patterns. When bail is set to true and a test fails, all remaining tests, both unit and functional, will be skipped. Other than the cleanup methods for the failing test and its containing suite, no other test or suite lifecycle methods (setup/before, before. Each, after. Each, teardown/after) will be run. Path (string) 3. 0. The common base path for all files that need to be loaded during testing. If base. Path is specified using a relative path, that path is resolved differently depending upon where Intern is executing: In Node. Path is resolved relative to process. In a browser with an initial. Base. Url argument in the query- string, base. Path is resolved relative to initial. Base. Url. In a browser with no initial. Base. Url argument, base. Path is resolved relative to two directories above the Intern directory (i. If it is not set properly for your application, the test runner will not work correctly. Variable (string) 3. The name of the global variable used to store and retrieve code coverage data. Change this only if you have code that is pre- instrumented by a compatible version of Istanbul with a different global variable name. Timeout (number) 3. The amount of time, in milliseconds, an asynchronous test can run before it is considered timed out. By default this value is 3. Timeouts can be set for an individual test by setting the timeout property of the test, or for all tests within a test suite by setting the timeout property of the suite. Instrumentation (Reg. Exp . The regular expression matches the path- part of URLs (starting from the end of proxy. Url, excluding any trailing slash) or paths (starting from the end of process. Node. js client. This option should be used when you want to exclude dependencies from being reported in your code coverage results. In Intern 3, forward- slashes should always be used regardless of platform. Reg. Exp)A regular expression that filters which tests should run. In other words, a test registered like this: tdd. Foo. Component', function () . In this case, all of the following grep values would match and cause this test to run: /Foo. Component//startup//Foo. Component - startup//foocomponent/i/start/The following grep values would not match and cause this test to be skipped: /Bar. Component/ . Any configuration options that are supported by the active loader can be used here. By default, the Dojo 2 AMD loader is used; this can be changed to another loader that provides an AMD- compatible API with loaders. AMD configuration options supported by the built- in loader are map, packages, and paths. If base. Url is not explicitly defined, it is automatically set to be equivalent to the base. Path. Relative base. Urls are relative to base. Path. When following the recommended directory structure, no extra loader configuration is needed. If you are testing an AMD application and need to use stub modules for testing, the map configuration option is the correct way to do this. When loaders is specified, Intern will swap out the built- in loader with the loader you. This should be a Node. ID. host- browser specifies the loader to use in browsers. This should be a path or URL to a script file. In Intern 2, loader paths are relative to the directory where Intern is installed. In Intern 3, loader paths are relative to base. Path. For example, to use a copy of Require. JS installed to the same project as Intern: loaders: . The file require. Web browsers only and will not work. Array< Object 3. Reporters in this list can either be built- in reporter names (like 'Console' or 'JUnit'), or absolute AMD module IDs (like 'tests/support/custom. Reporter') when using custom reporters. Reporters can also be configured by passing an object with extra configuration options valid for the given reporter. In this case, the ID of the reporter should be given by the id key of the reporter configuration. In Intern 3, reporter IDs are Upper. Camel. Case (because they are now constructors). Function)A function that will be run before the testing process starts. If this function returns a Promise, Intern will wait for the Promise to resolve before continuing. If the function throws an exception or rejects a returned Promise, the testing process will terminate with an error. This can be a good place to initialize testing resources needed by all tests, such as database connections. Array< string> )An array of unit test module IDs to load. Glob patterns must resolve to individual test modules, not packages. For example, given the following project structure, 'tests/u*' would not be a valid glob, but 'tests/unit/f*' would be: project.
