    int32 Occurrences
)

Remarks

Adds a regex pattern to an internal list that this test will expect to encounter in error or warning logs during its execution. If an expected pattern is not encountered, it will cause this test to fail.

Parameters

Parameter	Description
ExpectedPatternString	The expected message string. Supports basic regex patterns.
CompareType	How to match this string with an encountered error, should it match exactly or simply just contain the string.
Occurrences	How many times to expect this error string to be seen. If > 0, the error must be seen the exact number of times specified or the test will fail. If == 0, the error must be seen one or more times (with no upper limit) or the test will fail.
