runtime creation of functions in phpunit - phpunit

Question

Is there any way of creating testcases runtime by giving paramters?
Functionality of the test cases is same, just name and parameters will differ.
Like here is an example
public function testGetGiftsGivenVideo() {
$fileName = 'get-gifts-given-video.json';
$filePath = $this->path . $fileName;
$this->accessToken = $this->coreAPI->GetOAuthToken($this->loginFilePath);
$this->compareResults($filePath, $this->accessToken, true);
}
public function testGetGiftsReceivedAudio() {
$fileName = 'get-gifts-received-audio.json';
$filePath = $this->path . $fileName;
$this->accessToken = $this->coreAPI->GetOAuthToken($this->loginFilePath);
$this->compareResults($filePath, $this->accessToken, true);
}
public function testGetGiftsReceivedVideo() {
$fileName = 'get-gifts-received-video.json';
$filePath = $this->path . $fileName;
$this->accessToken = $this->coreAPI->GetOAuthToken($this->loginFilePath);
$this->compareResults($filePath, $this->accessToken, true);
}
Now all these functions are doing the same thing.

Answer 1

I see two possible solutions here:
As suggested by axiac in the comments, you can use data providers.
A data provider is a method returning an array of parameters to call a test method multiple times with different parameters. See the PHPUnit documentation about data providers for more information
/**
* #dataProvider provideGetGifts
* #param $filename
*/
public function testGetGifts($fileName) {
$filePath = $this->path . $fileName;
$this->accessToken = $this->coreAPI->GetOAuthToken($this->loginFilePath);
$this->compareResults($filePath, $this->accessToken, true);
}
public function provideGetGifts()
{
return array(
array('get-gifts-given-video.json'),
array('get-gifts-received-audio.json'),
array('get-gifts-received-video.json'),
);
}
The second solution, if you want to have different method names, is to simply use a second method which includes some logic of the test:
protected function compareAccessTokenWithFilePath($fileName) {
$filePath = $this->path . $fileName;
$this->accessToken = $this->coreAPI->GetOAuthToken($this->loginFilePath);
$this->compareResults($filePath, $this->accessToken, true);
}
public function testGetGiftsGivenVideo() {
$this->compareAccessTokenWithFilePath('get-gifts-given-video.json');
}
public function testGetGiftsReceivedAudio() {
$this->compareAccessTokenWithFilePath('get-gifts-given-audio.json');
}
public function testGetGiftsReceivedVideo() {
$this->compareAccessTokenWithFilePath('get-gifts-received-video.json');
}
Personally, I'd prefer the first solution. Its a little bit clearer.
