For 2021 - online Python 3 training - see ((here)).
Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.
Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.
Testing code coverage (have I tested everything?) in PHP
When you write a series of tests for your code and they all pass, have you tested everything? Not Necessarily - you only know that you have passed all the tests that you set, and not that the test set could be considered to be complete.
PHPUnit - the unit test suite for PHP - includes a coverage option which will let you check whether each class and method of the code that you're testing has been run as a part of the tests, and will tell you how many times each statement has been executed during testing. Simply run the phpunit command with the appropriate option:
phpunit --coverage-html /var/www/html/cover five.php
As the results are extensive, they don't come as a single file but rather as a complete web folder, and in my command I've redirected that to a directory that's within my web document root so that I can browse to it:
And I can also explore the source code and the number of times each conditional group of statements / loop has been run:
For details of writing the tests for PHPunit, see previous article [here]
