unittest parametric 3 - DDT (Mushishi "selenium3 automated testing combat - based on the Python language note 38")

DDT: Data-Drivern Tests against unittest extension library. Allows the use of different test data to run a test , and by displaying a plurality of test cases

 1. Online Download

In Dos input:

python -m pip install ddt

Successful installation results:

 

 2. Use DDT5 different parametric manner Baidu search

The parametric json 4: (ddt_data_file.json)

{
    "case1":{"search_key": "selenium"}, 
    "case2":{"search_key": "unittest"}, 
    "case3":{"search_key": "python"}
}

Parametric 5 yaml: (ddt_data_file.yaml)

case1:
- search_key: "python"
case2:
- search_key: "unittest"
case3:
- search_key: "ddt"

Note: If you do not install yaml, unable to perform parametric 5

Dos command-line installation:

python -m pip install pyyaml
