Error Codes
When Mocha itself throws exception, the associated Error will have a code property.
Where applicable, consumers should check the code property instead of string-matching against the message property.
The following table describes these error codes:
| Code | Description |
|---|---|
ERR_MOCHA_INVALID_ARG_TYPE | wrong type was passed for a given argument |
ERR_MOCHA_INVALID_ARG_VALUE | invalid or unsupported value was passed for a given argument |
ERR_MOCHA_INVALID_EXCEPTION | a falsy or otherwise underspecified exception was thrown |
ERR_MOCHA_INVALID_INTERFACE | interface specified in options not found |
ERR_MOCHA_INVALID_REPORTER | reporter specified in options not found |
ERR_MOCHA_NO_FILES_MATCH_PATTERN | test file(s) could not be found |
ERR_MOCHA_UNSUPPORTED | requested behavior, option, or parameter is unsupported |
