flake8-assertAlmostEqual

A Flake8 plugin to check for the use of round() in assertEqual and assertAlmostEqual.

It detects and flags two issues:

• AAE100 Don't use 'assertAlmostEqual' with 'round'. Use it's implemented rounding.
• AAE110 Don't use 'assertEqual' with 'round'. Use 'assertAlmostEqual' instead.

Don't use assertAlmostEqual with round... (AAE100)

assertAlmostEqual has built in rounding. Thus round() is not required.

Anti-pattern

assertAlmostEqual(round(my_result, 2), 1.52)

Best practice

assertAlmostEqual(my_result, 1.52, 2)

Don't use assertEqual with round... (AAE110)

If you need rounding, don't use assertEqual. Use assertAlmostEqual instead.

Anti-pattern

assertEqual(round(my_result, 2), 1.52)

Best practice

assertAlmostEqual(my_result, 1.52, 2)
