Log output and error messages

During execution TestApe will log test progress to the screen. Every error detected and every test execution is assigned a sequential identifier. Error identifiers are 3 digits shown prefixed by e, e.g. e001. Test identifiers are shown prefixed by t, e.g. t001.

These identifiers can be used from the commandline to limit the amount of test to run.

The log output can be disabled from commandline, but as default it is enabled and each log statement is prefixed with the tag TestApe and optionally the current test and/or error identifier as shown below.

When an error is detected TestApe will log information about the error. Generally a line for the actual and expected value. Only 8 values will be shown on each line, so when validating file content, strings, structs and arrays, several lines may be shown. Differences between actual and expected are indicated with the ^ sign as shown below.

testape:     actual ............ [000] 57 45 52 00             'WER.'
