Section 1.1: Utilize the @not Annotation

While exploring the Behave documentation, you may notice frequent references to the @use annotation. However, the @not annotation isn't highlighted as much, despite its significant utility. The @not annotation serves a similar purpose to @use, enabling you to exclude unwanted runs without the need to specify every option you wish to allow.

Section 1.2: Running Scenarios in Parallel

Behave does not natively support the parallel execution of feature files or scenarios, which can be a limitation. However, there are projects designed to facilitate this parallelism, like the one available on GitHub:

GitHub — hugeinc/behave-parallel: BDD, Python style, parallelism

If your budget allows, consider running multiple instances of Behave with varied settings using CI tools such as TeamCity, Jenkins, or Bamboo.

Section 1.3: Ensure Unique Gherkin Steps

When utilizing Gherkin syntax, it's essential that each step is distinct. You have several options like given, when, and then. However, if you create multiple files with identical method names, you may encounter conflicts. To address this, implement a nested folder structure that mirrors your testing objectives, which can also help streamline your step definitions.

Section 1.4: Watch Out for PyCharm Issues

Be cautious when executing specific scenarios with user-defined arguments in PyCharm. There is a known bug where it may incorrectly process arguments. For instance, using -D name="Jakub Jirák" will only pass "Jakub" as the argument name. Conversely, executing the command from the terminal will correctly handle the full name.

Section 1.5: Always Implement Filters

Utilizing filters is crucial to avoid executing unnecessary scenarios. For example, I developed a framework to verify the full purchase workflow on Digital River payment gateways in production. Neglecting to set appropriate filters could inadvertently block credit card or PayPal transactions due to limits being exceeded.
