![]() The principal is, we can change code of a unit test for applications but the application code will not be changed for a unit test. "The tests may change for code but the code will never change for tests.“". Ok, first of all let me clarify a principal of unit testing. To make DB operations we will use Entity Framework. ![]() So the fundamental idea of unit testing is needed and in this example we will implement a Mock object using the Moq framework, so a prior concept of mocking will help you to understand the article fully. ![]() The purpose of this article is to explain how dependency injection helps unit testing in applications. Unit testing is tremendously easy when we implement Dependency injection in applications. And another point behind de-coupling architecture is unit testing. We know that, dependency injection is one of the important parts of application development when we want to do de-coupled architecture. ![]() Fundamentals of Unit Testing: Unit Testing of IOC Code.Fundamentals of Unit Testing: Understand Mock Object in Unit Testing.Fundamentals of Unit Testing: Unit Test Using Nunit.Fundamentals of Unit Testing: Don't Test Your Private Method.Fundamentals of Unit Testing: Understand ExpectedException in Unit Testing.Fundamentals of Unit Testing: Understand CollectionAssert() in Unit Testing.Fundamental of Unit Testing: Test Initialize and Test Setup.Fundamental of Unit Testing: Understand AreEqual and AreEqual in Unit Testing.Fundamentals of Unit Testing: Understand AAA in Unit Testing.Fundamentals of Unit Testing: Test Your Application by Visual Studio Unit Test.Fundamentals of Unit Testing: Getting Started With Unit Testing.In our previous article we covered various concepts of unit testing in a Visual Studio unit test project and in third-party unit test libraries like Nunit. Projects can be also used to parametrize tests with your custom configuration - take a look at this separate guide.This is another article in this series. In other words, if a matching test belongs to a project that has project dependencies, Playwright will run all the tests from the project depdencies ignoring the filters. If -grep/-grep-invert option is used, test file name filter is specified in command line or test.only() is used, the will only apply to the tests from the deepest projects in the project dependency chain. See the teardown guide for more information. Teardown will run after all dependent projects have run. You can also teardown your setup by adding a testProject.teardown property to your setup project. Tests in the 'Browser Login' and 'DataBase' projects run in parallel:.If the tests from a dependency fails then the tests that rely on this project will not be run. If there are more than one dependency then these project dependencies will be run first and in parallel. By default, these projects will run in parallel, subject to the maximum workers limit. Tests in the 'chromium', 'webkit' and 'firefox' projects run together. Once all tests from this project have passed, then the tests from the dependent projects will start running. When working with tests that have a dependency, the dependency will always run first and once all tests from this project have passed, then the other projects will run in parallel. See the registry of device parameters for a complete list of selected desktop, tablet and mobile devices. Playwright can also run on emulated tablet and mobile devices. Configure projects for multiple browsers īy using projects you can run your tests in multiple browsers such as chromium, webkit and firefox as well as branded browsers such as Google Chrome and Microsoft Edge. For example, you can run the same tests in a logged-in and logged-out state.īy setting up projects you can also run a group of tests with different timeouts or retries or a group of tests against different environments such as staging and production, splitting tests per package/functionality and more. You can also use projects to run the same tests in different configurations. Projects are configured in the file and once configured you can then run your tests on all projects or only on a specific project. We use projects so we can run tests on different browsers and devices. A project is logical group of tests running with the same configuration.
