assert_checkerror

Check that an command raises the expected error.

Syntax

• assert_checkerror(command, expected_error_message)
• r = assert_checkerror(command, expected_error_message)
• [r, msg] = assert_checkerror(command, expected_error_message)
• assert_checkerror(command, expected_error_message, expected_error_identifier)
• r = assert_checkerror(command, expected_error_message, expected_error_identifier)
• [r, msg] = assert_checkerror(command, expected_error_message, expected_error_identifier)

Input argument

• command - a string value
• expected_error_message - a string, the expected error message.
• expected_error_identifier - a string, the expected error identifier.

Output argument

• res - a logical value
• msg - a string value, the error message. If res == true, then errormsg == ''. If res == false, then msg contains the error message.

Description

If the command does not raise the expected error message, then assert_checkerror raises an error.

Examples

assert_checkerror('cos', _('Wrong number of input arguments.'));

assert_checkerror('cos', _('Wrong error message.'));

assert_checkerror('mustBeFinite(NaN)', _('Value must be finite.'), 'Nelson:validators:mustBeFinite')
