# Functional Testing
|
|
|
|
[FunctionalTest](api:SilverStripe\Dev\FunctionalTest) test your applications `Controller` logic and anything else which requires a web request. The
|
|
core idea of these tests is the same as `SapphireTest` unit tests but `FunctionalTest` adds several methods for
|
|
creating [HTTPRequest](api:SilverStripe\Control\HTTPRequest), receiving [HTTPResponse](api:SilverStripe\Control\HTTPResponse) objects and modifying the current user session.
|
|
|
|
## Get
|
|
|
|
```php
|
|
$page = $this->get($url);
|
|
```
|
|
|
|
Performs a GET request on $url and retrieves the [HTTPResponse](api:SilverStripe\Control\HTTPResponse). This also changes the current page to the value
|
|
of the response.
|
|
|
|
## Post
|
|
```php
|
|
$page = $this->post($url);
|
|
```
|
|
|
|
Performs a POST request on $url and retrieves the [HTTPResponse](api:SilverStripe\Control\HTTPResponse). This also changes the current page to the value
|
|
of the response.
|
|
|
|
<div class="notice" markdown="1">
|
|
**Compatibility Notice:** Previous versions of SilverStripe would send a GET request if `post()` was called with no POST variables supplied in the second argument.
|
|
SilverStripe 4.6 and later always sends a POST request for consistency.
|
|
</div>
|
|
|
|
## Other Requests
|
|
```php
|
|
$page = $this->sendRequest('PUT', $url);
|
|
```
|
|
|
|
Performs a request on $url with the HTTP method provided (useful for PUT, PATCH, DELETE, etc.). This also changes the current page to the value of the response.
|
|
|
|
## Submit
|
|
|
|
|
|
```php
|
|
$submit = $this->submitForm($formID, $button = null, $data = []);
|
|
```
|
|
|
|
Submits the given form (`#ContactForm`) on the current page and returns the [HTTPResponse](api:SilverStripe\Control\HTTPResponse).
|
|
|
|
## LogInAs
|
|
|
|
|
|
```php
|
|
$this->logInAs($member);
|
|
```
|
|
|
|
Logs a given user in, sets the current session. To log all users out pass `null` to the method.
|
|
|
|
|
|
```php
|
|
$this->logInAs(null);
|
|
```
|
|
|
|
## Assertions
|
|
|
|
The `FunctionalTest` class also provides additional asserts to validate your tests.
|
|
|
|
### assertPartialMatchBySelector
|
|
|
|
|
|
```php
|
|
$this->assertPartialMatchBySelector('p.good',[
|
|
'Test save was successful'
|
|
]);
|
|
```
|
|
|
|
Asserts that the most recently queried page contains a number of content tags specified by a CSS selector. The given CSS
|
|
selector will be applied to the HTML of the most recent page. The content of every matching tag will be examined. The
|
|
assertion fails if one of the expectedMatches fails to appear.
|
|
|
|
|
|
### assertExactMatchBySelector
|
|
|
|
|
|
```php
|
|
$this->assertExactMatchBySelector("#MyForm_ID p.error", [
|
|
"That email address is invalid."
|
|
]);
|
|
```
|
|
|
|
Asserts that the most recently queried page contains a number of content tags specified by a CSS selector. The given CSS
|
|
selector will be applied to the HTML of the most recent page. The full HTML of every matching tag will be examined. The
|
|
assertion fails if one of the expectedMatches fails to appear.
|
|
|
|
### assertPartialHTMLMatchBySelector
|
|
|
|
```php
|
|
$this->assertPartialHTMLMatchBySelector("#MyForm_ID p.error", [
|
|
"That email address is invalid."
|
|
]);
|
|
```
|
|
|
|
Assert that the most recently queried page contains a number of content tags specified by a CSS selector. The given CSS
|
|
selector will be applied to the HTML of the most recent page. The content of every matching tag will be examined. The
|
|
assertion fails if one of the expectedMatches fails to appear.
|
|
|
|
[notice]
|
|
`&nbsp;` characters are stripped from the content; make sure that your assertions take this into account.

|

|
|
### assertExactHTMLMatchBySelector
|
|
```php
|
|
$this->assertExactHTMLMatchBySelector("#MyForm_ID p.error", [
|
|
"That email address is invalid."
|
|
]);
|
|
```
|
|
|
|
Assert that the most recently queried page contains a number of content tags specified by a CSS selector. The given CSS
|
|

|
|
