httprunner parametric study 6- (reference external data csv)

Foreword

Previous parameterization has been achieved, but the data is on file .yml inside, when a lot of test data, we hope to test data is written to a csv file.

Independent parameters

For existing parameter list, and the large amount of data, the more suitable manner the parameter value list is stored in the CSV data file.

For the CSV data file, you need to follow a few rules agreed as follows:

• File should be placed in the same directory as the test case file;
• The first row of the CSV file must be the name of the parameter, the second parameter value is a start line, each (set) value of a line;
• If a plurality of parameters having the same CSV file, parameter names and values ​​Spacer Needed commas.

For example, user_id parameter ranges from 1001 to 2000, then we can create user_id.csv, and described as follows in the form of a file.

user_id
1001
1002
...
1999
2000

Then YAML / JSON test file, it can be built to Parameterize (may be abbreviated as P) function references a CSV file.

- config:
    parameters:
        - user_id: ${parameterize(user_id.csv)}
        - user_id: ${P(user_id.csv)}    # 简写方式

csv file to store user data

To prepare test data, prepare four sets of login with account and password, the account is test1, test2, test3, test4, a unified password is set to 123456.

user_name.csv test data file

user
test1
test2
test3
test4

user_name.csv test_param_csv.yml files and files into the same directory, references csv file syntax${P(user_name.csv)}

V1.x versions of the test data csv file can only be a test case files in the same directory, V2.x version supports write path to the file path for the project root directory (the path debugtalk.py) based on the relative path. Such as: data / user_id.csv
