PHP-Tester

A PHP testing lib that works through both web & cli

Features

Output tests to HTML:
1. Wrapped in <details> tag for vanilla-html expand/collapse
2. Pass/Fail/Success (colorized)
3. Any echo/printed content from each test is shown
4. Exceptions in tests are caught & printed
5. Source is well-formatted so you can view-source OR view it in a browser
Extend the tester class & every method starting with test will be run as a test

TODO

Priority TODO

Add functional testing option
- $t = new \Taeluf\Tester(); $t->startTest(); doSomeCode(); $t->endTest('name');
Add basic test benchmarking
Add equality testing function
- $succeeded = $this->test('expectedOutput', $actualOutput);
- print "target: ..." & "actual: ..."
- Handle printing of strings & arrays, maybe other stuff. Maybe just var_dump?? (ugly)

Maybe Eventually TODO

Pick a better name
Self-promo, maybe? Document it on my website & direct folks there, share my twitter handle, patreon, etc
Add sub-tests (not sure what I mean here?? But it's in my notes!)
Store test code in arrays & output it in the HTML for each test
- Use debug_backtrace() or tokenizing or something to get the line of each testFunction & just copy the code from the function & include it in the HTML output
- This should DEFINITELY be optional

Example (OOP Style)

We'll create a simple "translator" function & test it with the OOP approach.

"translation" function:

function translateGreeting($language){
    switch ($language){
        case "spanish":return "Hola";
        case "german": return "Hallo";
        case "english": return "Hello";
        case "french": return "Bonjour";
        default: return null;
    }
}

"Tester" class:

class TranslatorTester extends \Taeluf\Tester{

    //every function that starts with `test` will be run as a test
    public function testTranslateSpanish(){
        $actual = translateGreeting('spanish');
        $target = "Hola";
        echo "Target:{$target}\nActual:{$actual}";
        if ($target==$actual)return true;
    }
    public function prepare(){
        //this code runs BEFORE any of your test code
    }
    //You can declare other functions that DON'T start with `test` if you need helper functions.
}
//TranslatorTester::runAll() // just print the results
//TranslatorTester::run(['testTranslateSpanish']) // run every test method given in that array
// (new TranslatorTester())->run(); //runs all this way, or pass an array of methods to only run those tests
TranslatorTester::runAllToFile(__FILE__.'.html',$alsoPrint=true);
TranslatorTester::xdotoolRefreshFirefox(); // If you have xdotool installed, this will switch to Firefox & refresh focused webpage.

Output:

You can copy the path to the html file & paste it in your browser bar to view your test result

HTML Code

<details>
    <summary><b>TranslateSpanish:</b> <span style="color:green;">success</span>    </summary>
    <div style='padding-left:4ch;white-space:pre;'>
        Target:Hola
        Actual:Hola
    </div>
</details>

Visual

Markdown strips the inline styles, so it lacks the colors & white-space:pre

TranslateSpanish: success

        Target:Hola
        Actual:Hola
    

Contribution

PHP code is in 5-src dir. Put tests in 8-build/test/. Probably use a sub-directory. Look at my Translator test and see Docu Bear to learn how to document. Orr... just write some code & I'll probably document it up.
