Syntax
TestCheckNull(<Expression> [, <Comments> [, <Parameter 1> [... [, <Parameter N>]]]])
<Expression>: Character string Expression that must be checked. <Comments>: Character string Character string in the format defined by StringBuild. <Parameter 1>: Any type First parameter expected by <Comments>. <Parameter N>: Any type Nth parameter expected by <Comments>. Remarks Operating mode When the expression is not Null:   in automated test mode, an error is added to the test status report (equivalent to TestWriteResult). - in manual test mode, an assertion is displayed (equivalent to dbgAssert).
- in runtime mode, an assertion is displayed if the assertions have been enabled (equivalent to dbgAssert).
When running an application, the expression is not evaluated if the assertions are not enabled. dbgOnError allows you to automatically start a WLanguage procedure used to retrieve the comment linked to the error.
