As I introduced before, it’s the easiest change and improves a lot your code. In this article, I focus on the first part: the writing style. Given-When-Then: Tests that a human can readīDD brings to the table not only a human-friendly style of writing test scenarios but also the important idea that you should be doing that before writing the code that implements your functionality (thereby the name Behavior-Driven Development). The tests may be working perfectly and covering that functionality as it’s needed but, not being able to derive the application flow from their code is a clear symptom of bad readability of your Unit Tests, that makes them harder (and more expensive) to maintain. There is even a worse scenario in which, apart from the tests, you also count with documentation for that specific functionality but you have no idea how the code maps to those requirements. However, if the test is a mess, that task is much more complicated (or near impossible in some cases). As a developer, I use Unit Tests to understand the functionality that someone else has written before. If you have many unit tests (good!), maintaining them is hard. The code in Unit Tests tends to be disorganized: some mocks here and there, interleaved with assertions and test method calls. If you find it useful, please give it a star! Why should I use BDD? Reverse Engineering in non-BDD tests The docker images command is used to list all containers and the -q option is provided to list only container IDs.All the code in this post is available on GitHub: Tests with BDD Mockito and AssertJ. The docker rmi command can be used to remove all docker images. ![]() $ docker rm $(docker ps -a -q) Remove All Docker Container ImagesĪfter stopping running containers we may need to remove all docker images as we do not need them anymore. The container should be in a stopped state which is described above. $ docker kill $(docker ps -q -filter "name=postgre") Remove All Docker ContainersĪll existing docker containers can be removed with the docker rm command. For example, if we need to stop all docker containers those names contain “postgre” we can use the following command where -filter option is used to filter running containers according to their names. In some cases, we may need to stop all running docker containers with a specific name. $ docker ps Stop All Docker Containers with Specified Name $ docker kill $(docker ps -q) Check If All Docker Containers StoppedĪfter using the “docker kill” or “docker stop” commands to stop all running containers we can check if all dockers are stopped properly by using the “docker ps” command. Actually, the “docker kill” command is very similar to the “docker stop” command where the “docker top” command sends SIGTERM but the “docker kill” command sends SIGKILL signal for all running docker containers. Stop All Docker Containers with “docker kill”Īnother way to stop all running docker containers is using the docker kill command. The “docker stop” command stops all provided IDs. The -q flag only lists the docker containing IDs and this ID list is provided to the “docker stop” command. We will use the docker ps -q command in order to provide all running docker names to the “docker stop” command. The “docker stop” command syntax requires where the docker name is provided. Stop All Docker Containers with “docker stop”ĭocker provides the docker stop command in order to stop provided containers. In this tutorial, we provide different ways to stop all docker containers. In some cases, we may need to stop all currently running containers in an easy way with a single command. Docker can run multiple containers at the same time.
