![]() environment="ci.postman_environment.json" Newman run ci-demo.postman_collection.json If you need to get up to speed on docker-compose you can do so here.Ĭreate a file named "docker-compose.yaml" in the base directory of your project with the following contents: We are going to use docker-compose to start our sample application, as well as the Newman CLI. We are now going to use the Postman CLI tool named "Newman" to execute the same API tests we just imported. You should now be able to execute your tests locally by selecting your "local" environment you just created and clicking "Send" on your various tests.Įxecuting API Tests With Newman and docker-compose The "Current Value" section should auto fill with what you entered for the initial value. In the "Variable" section enter "host_name" and for the "Initial Value" enter "localhost". For the name enter "local" and click the "Add a new variable" text. To do this click on the gear in the top right of the screen to get to the "Manage Environments" screen and click the "Add" button. The next thing we need to do to allow our tests to be executed locally is to create a local environment configured with our local environment settings. This is important for using this in CI because later when these tests are executed in docker-compose the hostname is going to be a different value than when you execute these tests locally. The URL in our tests is actually " This is because Postman allows for variables to be defined for a particular environment and you can change between them in the top right of the screen. You may have noticed that the URL we are testing has some variables in it. ![]() These are just very simple examples but there are many more to explore by clicking on the "SNIPPETS" in the right side or by writing your own. It is also verifying that the body returned should not contain the value of "Mark". You can see that this particular test is verifying that a GET call to /newkids should return a 200 response code and the body returned should contain the value of "Donnie". Your screen should now look like this:Ĭlick the "Import" button and you should see your collection on the left side of the screen.Įxpanding the collection and selecting one of the tests should allow you to then select the "Tests" tab and should look like this: You can either drag and drop the file or click in the window and select your "" file. To do this we will create a new Collection while importing it by clicking on the "Import" button in the top left. The next thing we are going to do is import our tests into the Postman application. "tests = !responseBody.has(\"Mark\") "Īlso in the api-tests directory create a file named "ci.postman_environment.json" that contains the following JSON: "var jsonData = JSON.parse(responseBody) ", "tests = responseBody.has(\"Not Implemented\") ", Create a file named index.js that contains the following code: It will be a node app using Express to keep it simple. For this exercise we will be making a API that returns members of boy-bands. We need to start with an example application. Let's take a look at how to accomplish this. Verifying that the running container can pass automated tests as early in the pipeline as possible is a very good thing. Automated tests are written in javascript and will be executed in the PostMan CLI tool called Newman. We will build a simple express REST API application based on a Node image and then execute and verify automated tests against the api by running the application in docker-compose. ![]() In this article we will walk through a demo of a GitLab CI/CD pipeline. After an image is built and can be started and tested to decide if it is a viable candidate to push to the registry. ![]() One thing to be aware of it is will download node for the system it is being run on, so if you have a different OS on your build server, you'll need to make sure that is the version you have checked into version control, your local version (for me OSX) will have to be maintained local to your project.Executing automated tests in a CI/CD pipeline can be made simple and easy when using containers. This is how i use it for Grunt but it supports Gulp just as well. In my experience, the frontend maven plugin is far and away the best plugin for this type of build/deploy process. ![]()
