Why data-driven tests increase coverage in Selenium Python - Test Your Understanding

Practice - 5 Tasks

1fill in blank

easy

Complete the code to run the test with multiple data inputs.

Selenium Python

for data in [1]:
    result = process(data)
    assert result == expected

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

Aprocess_data

Binput_data

Cdata_list

Dtest_data

💡 Hint

Common Mistakes

Using a single data item instead of a collection.

Using an undefined variable name.

The variable 'test_data' holds the multiple inputs for the data-driven test loop.

2fill in blank

medium

Complete the code to assert the expected output for each input.

Selenium Python

assert [1] == expected_output

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

Aoutput

Bresult

Cinput_value

Ddata

Attempts:

3 left

💡 Hint

Common Mistakes

Asserting the input instead of the output.

Using a variable that is not defined.

The variable 'result' holds the actual output to compare with the expected output.

3fill in blank

hard

Fix the error in the test function to correctly use data-driven testing.

Selenium Python

def test_function():
    for item in [1]:
        output = process(item)
        assert output == expected

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

Atest_cases

Btest_case

Ctestcase

Dtestcase_list

Attempts:

3 left

💡 Hint

Common Mistakes

Using a singular variable name that is not iterable.

Using an undefined variable.

The variable 'test_cases' correctly refers to the collection of inputs for the loop.

4fill in blank

hard

Fill both blanks to create a data-driven test that iterates and asserts correctly.

Selenium Python

for [1] in test_data:
    result = process([2])
    assert result == expected

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

Aitem

Bdata

Cinput

Dvalue

Attempts:

3 left

💡 Hint

Common Mistakes

Using different variable names for loop and function input.

Using a variable not defined in the loop.

The loop variable 'item' is used both to iterate and as input to the process function.

5fill in blank

hard

Fill all three blanks to build a data-driven test with a descriptive assertion message.

Selenium Python

for [1] in test_inputs:
    output = process([2])
    assert output == expected, f"Failed for input: [3]"

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

Atest_input

Dinput_value

Attempts:

3 left

💡 Hint

Common Mistakes

Using different variable names causing confusion.

Leaving the assertion message without the input variable.

Using 'test_input' consistently for the loop variable, function input, and message shows clear data flow.
