class twisted.trial.runner.ErrorHolder(TestHolder): (source)
Used to insert arbitrary errors into a test suite run. Provides enough methods to look like a TestCase, however, when it is run, it simply adds an error to the TestResult. The most common use-case is for when a module fails to import.

Inherited from TestHolder:
| Class Variable | failureException | The exception class that is raised by failed assertions |
| Instance Variable | description | Undocumented |
| Method | __call__ | Run the test. Should always do exactly the same thing as run(). |

| Method | countTestCases | Return the number of tests in this test case. Usually 1. |
| Method | shortDescription | Return a short description of the test. |
| Parameters | description | A string used by TestResults to identify this error. Generally, this is the name of a module that failed to import. |
| error | The error to be added to the result. Can be an `exc_info` tuple or a twisted.python.failure.Failure. |
Run the test, reporting the error.
| Parameters | result | The TestResult to store the results in. (type: twisted.trial.itrial.IReporter.) |
