Identifying Test Files using Pytest
We can identify test files by using Pytest. Below is the syntax of this.
Syntax: pytest -k substring_match -v
Here,
- substring_match: It is the substring to be matched while executing the tests in Pytest.
File Structure
Example 1
In this example, we have created a package fastapi3, in which we have created two Python files, test_1.py and gfg.py. When we will run the tests, we will see only the tests of the file starting with test_, i.e., test_1.py will be executed.
Python3
# Importing the math libraryimport math# Creating first test casedef test_check_floor(): num = 6 assert num==math.floor(6.34532)# Creating second test casedef test_check_equal(): assert 50 == 49 |
gfg.py: Here, we are creating 2 test cases.
Python3
# Importing the math libraryimport math# Creating first test casedef test_check_difference(): assert 99-43==57# Creating second test casedef test_check_square_root(): val=8 assert val==math.sqrt(81) |
Output
Now, we will run the following command with substring_match as check as follows:
pytest -k check -v

Identifying Test files and Functions using Pytest
The Python framework used for API testing is called Pytest. For executing and running the tests, it is crucial to identify the test files and functions. Pytest, by default, executes all the test files under a certain package which are of the format test_*.py or *_test.py, in case there is no test file mentioned. Similarly, for functions, all the functions of format test* are executed in case no function is specified.
