Individual assert-logs() Attributes

expected-log:

  • An object.  An instance of assert-log common properties.

expected-logs:

assertion-mode:

failure-id:

  • Identifier to use as a Failure ID if the log assertion fails.

log-defaults:

  • An object.  It is an instance of assert-log common properties.
  • Any log-defaults property not specified for one of the expected logs will be applied as though it were specified.

Example

Location of expected-log-file Log Excerpt Files

 

assert-logs Code Example

  • In the example below, all the expected-log conditions must be true, or the test will fail. 
  • This is because match-all was specified for assertion-mode.
  • In this example, there is actually only one log file, the one specified in log-name-pattern.
  • The expected-log-file refers to a file that contains an excerpt of text, usually spanning several lines, that you expect to find in the log file.
