pytest.approx

pytest.approx is a utility provided by the pytest testing framework. It is used to perform approximate comparisons between floating-point values.

When writing tests for floating-point values, it is often impractical to expect exact equality due to rounding errors. pytest.approx allows you to specify a tolerance within which the values should be considered approximately equal.

Here's an example usage of pytest.approx:

def test_approximate_comparison():
    assert 0.1 + 0.2 == pytest.approx(0.3)

In this example, instead of checking for exact equality, we use pytest.approx to compare the sum of 0.1 and 0.2 with the expected value of 0.3. The assertion will pass because pytest.approx takes into account a default tolerance for floating-point comparisons.

You can also specify a custom tolerance by providing a second argument to pytest.approx, like this:

def test_custom_tolerance():
    assert 0.1 + 0.2 == pytest.approx(0.3, abs=1e-6)

In this case, we set the absolute tolerance to 1e-6, meaning that the values will be considered approximately equal if their difference is within this tolerance.

Overall, pytest.approx is a useful tool for performing approximate comparisons in tests involving floating-point numbers, helping to handle the inherent imprecision of floating-point arithmetic.

pairwise方法软件测试

Pairwise testing, also known as all-pairs testing, is a software testing technique that involves testing all possible unique combinations of input parameters or variables, to ensure that the software works correctly and to minimize the number of test cases needed.

The pairwise method works by creating a matrix or table that shows all possible combinations of the input variables. Then, the tester selects a subset of those combinations that will cover all possible pairs of values for each input variable.

This method is particularly useful when there are many input variables and testing all possible combinations would be impractical. By selecting only the necessary combinations, the testing process becomes more efficient and effective.

There are several software tools available for pairwise testing, such as PICT, Jenny, and AETG. These tools can help automate the process of generating test cases and ensure that all possible combinations are covered.

Overall, pairwise testing is a valuable technique for software testers looking to improve their testing process and ensure that their software is functioning correctly.
