lettuce

The official version of lettuce is a driver development package suitable for Python. The latest version of lettuce supports international official languages ​​and stipulates a series of grammars. Users only need to tell it according to its rules, and the software can understand your needs. Lettuce software is a python usage Lettuce test automation driver specially created for developers. It is suitable for the communication between BA and Tester in current agile development.

Introduction to lettuce software

Lettuce is another behavior-driven automation tool based on Cucumber and Python. Lettuce focuses on common tasks that characterize behavior-driven development. Not only is it easy to use, but it can make the entire testing process smoother and even more fun.

Advantages of lettuce software

​​Similar to other BDD testing frameworks, Lettuce allows developers to create multiple scenarios and use simple natural language to describe different functions.

​​ ​ Based on similar specification formats, development and QA teams can coordinate and collaborate.

For black box testing, Lettuce is very suitable for behavior-driven test cases.

lettuce instructions for use

​ ​ 1. pip install lettuce installed under Python2.7

2. py -3 –m pip install lettuce installed under Python3

3. Execution: Go to the superior directory of the feature, execute cmd, then execute lettuce, and press Enter

4. Behavior-driven: Each natural language corresponds to a case; generally used in agile development. The advantage is that there is a connection between all test cases and natural language, and you can clearly see the results of each test case execution.

5. Test case explanation written in natural language

​​ 6. Basic ideas of behavior-driven:

(1) Get data

(2) Call the test method with test data

(3) Assert whether the test results are consistent with the expected results

7. Some special processing in behavior drivers implemented using classes

(1) exclude = ['set_number', 'get_number'] defines which methods do not need to be executed

(2) def _assert_number_is(self, expected, msg="Got %d"): Private methods are not test steps by default

(3) step.hashes can automatically obtain data in tabular form defined through natural language, and returns a list

(4) If the feature file is in Chinese, you must add this # language: zh-CN
