Deployment terms in Open Event Frontend
In Open Event Frontend, once a pull request is opened, we see some tests running on for the specific pull request like ‘Codacy’, ‘Codecov’, ‘Travis’, etc. New contributors eventually get confused what the tests are about. So this blog would be a walkthrough to these terms that we use and what they mean about the PR.
Travis: Everytime you make a pull request, you will see this test running and in some time giving the output whether the test passed or failed. Travis is the continuous integration test that we are using to test that the changes that the pull request you proposed does not break any other things. Sometimes you will see the following message which indicates that your changes is breaking something else which is not intended.
Thus, by looking at the Travis logs, you can see where the changes proposed in the pull request are breaking things. Thus, you can go ahead and correct the code and push again to run the Travis build until it passes.
Codacy: Codacy is being used to check the code style, duplication, complexity and coverage, etc. When you create a pull request or update the pull request, this test runs which checks whether the code followed certain style guide or if there is duplication in code, etc. For instance let’s say if your code has a html page in which a tag has an attribute which is left undefined. Then codacy will be throwing error failing the tests. Thus you need to see the logs and go correct the bug in code. The following message shows that the codacy test has passed.
Codecov is a code coverage test which indicates how much of the code change that is proposed in the pull request is actually executed. Consider out of the 100 lines of code that you wrote, only 80 lines is being actually executed and rest is not, then the code coverage decreases. The following indicates the codecov report.
Thus, it can be seen that which files are affected by what percent.
The surge link is nothing but the deployment link of the changes in your pull request.
Thus, checking the link manually, we can test the behavior of the app in terms of UI/UX or the other features that the pull request adds.
