Tutorial 15 – Tags in Behave BDD
Welcome to the 15th article in Behave BDD series!
What you will Learn :
Importance of Tags
Execute @Smoke test
Execute 2 tags seperated by comma (logical OR)
Execute 2 tags seperated by several --tags (logical AND)
Use ~ to ignore scenario execution
Importance of Tags
We can do some excellent things when we execute our test cases with Behave BDD. We can tag sanity based test cases, smoke test cases, regression test cases etc.
To further understand the tags, let us create a new feature file having 3 scenarios
So far, we haven’t added any tags to our feature file.
Let us create the corresponding step definition file for the above feature file
Save the file.
Let us run the feature file to ensure there are no errors
So there are no errors in execution.
We will now create 3 tags in our feature file for all the 3 scenarios, see below 
Save the file and execute the feature file once again. Notice below that all the scenarios get executed as expected
Execute @Smoke test
We will now see how to run only ‘smoke’ based test case/scenario. The syntax is as mentioned below:
behave filename.feature --tags=tagname
Notice above that only @smoke scenario got executed (the summary result says 2 skipped and we see # None against the 6 steps).
Let us now change the tag to @Integration. Notice below that this time only @integration scenario got executed
Execute 2 tags seperated by comma (logical OR)
You can execute 2 tags together as well by separating the tagnames by comma (logical ‘OR’). So below we are executing those test cases which are tagged with @Smoke or @Regression
Similarly, see below. We do not have @Unit test case and hence only @Integration gets executed
Similarly you can try executing more than 2 tags as well.
Execute 2 tags seperated by several --tags (logical AND)
Let us represent the second scenario using 2 tags: @Regression @Production (see below)
Save the file.
Now how we run a scenario that has 2 tags attached to it?
See below and notice that only one scenario gets executed that has both the tags
Use ~ to ignore scenario execution
Let us remove the @Production tag from second scenario
Save the file
Let us say we want to execute all the scenarios except @Smoke. We can do that using ~ (tilde), see below
Notice above that @Smoke did not execute.
So this is how we can use tags in our feature files.
Thank you for reading!
