Root Cause

Using @unittest.skip without providing a reason string, or using it as a bare decorator without parentheses, causing a TypeError.

generic

中文

使用 @unittest.skip 时未提供原因字符串，或将其作为无括号的裸装饰器使用，导致 TypeError。

Workarounds

  1. 95% success 
    Use @unittest.skip('reason') with a string argument, e.g., @unittest.skip('Not implemented yet')
  2. 90% success 
    Alternatively, use @unittest.skipIf(condition, 'reason') to skip conditionally.

Dead Ends

Common approaches that don't work:

  1. 70% fail

    Adding parentheses but no argument (e.g., @unittest.skip()) still fails because reason is required.

  2. 60% fail

    Using @unittest.skipIf(condition) without a reason also fails because reason is required for skipIf.
