Complete the code to import the regression testing module.

💡 Hint

Common Mistakes

Importing unittest or pytest instead of the regression testing module.

The regression_testing module is used to perform regression tests to ensure software changes do not break existing functionality.

Complete the code to run regression tests on the model.

Software Engineering

result = regression_testing.run([1])

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Passing data or metrics instead of the model to the regression test.

The run function takes the model as input to perform regression testing on it.

Fix the error in the regression test assertion.

Software Engineering

assert [1] == expected_output, "Regression test failed"

Drag options to blanks, or click blank then click option'

Cmodel

Dresult

💡 Hint

Common Mistakes

Using variables like output or model which are not the test result.

The variable result holds the output of the regression test and should be compared to the expected output.

4fill in blank

hard

Fill both blanks to create a regression test function that returns True if tests pass.

Software Engineering

def regression_test_[1]():
    result = run_test()
    return result [2] expected

Drag options to blanks, or click blank then click option'

Afunction

B==

C!=

💡 Hint

Common Mistakes

Using '!=' instead of '==' for comparison.

Using incorrect function name parts.

The function name should be regression_test_function and it returns True if result == expected.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps test names to pass status.

Software Engineering

test_results = [1]: run_test([2]) [3] [2] in test_names

Drag options to blanks, or click blank then click option'

A{name

Bname

Cfor

💡 Hint

Common Mistakes

Missing curly brace or using wrong keywords in comprehension.

The dictionary comprehension starts with {name, iterates for over test_names, and calls run_test(name).
