FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Writing Tests
Imagine that we are testing this simple class:
So we create test file named greeting.test.phpt:
Thats' all!
Now we run tests from command-line using the tester command:
Nette Tester prints dot for successful test, F for failed test and S when the test has been skipped.
Assertions
This table shows all assertions (class Assert means Tester\Assert):
Assert::same($expected, $actual)- Reports an error if $expected and $actual are not the same.Assert::notSame($expected, $actual)- Reports an error if $expected and $actual are the same.Assert::equal($expected, $actual)- Like same(), but identity of objects and the order of keys in the arrays are ignored.Assert::notEqual($expected, $actual)- Like notSame(), but identity of objects and arrays order are ignored.Assert::contains($needle, array $haystack)- Reports an error if $needle is not an element of $haystack.Assert::contains($needle, string $haystack)- Reports an error if $needle is not a substring of $haystack.Assert::notContains($needle, array $haystack)- Reports an error if $needle is an element of $haystack.Assert::notContains($needle, string $haystack)- Reports an error if $needle is a substring of $haystack.Assert::true($value)- Reports an error if $value is not true.Assert::false($value)- Reports an error if $value is not false.Assert::truthy($value)- Reports an error if $value is not truthy.Assert::falsey($value)- Reports an error if $value is not falsey.Assert::null($value)- Reports an error if $value is not null.Assert::nan($value)- Reports an error if $value is not NAN.Assert::type($type, $value)- Reports an error if the variable $value is not of PHP or class type $type.Assert::exception($closure, $class, $message = null, $code = null)- Checks if the function throws exception.Assert::error($closure, $level, $message = null)- Checks if the function $closure throws PHP warning/notice/error.Assert::noError($closure)- Checks that the function $closure does not throw PHP warning/notice/error or exception.Assert::match($pattern, $value)- Compares result using regular expression or mask.Assert::matchFile($file, $value)- Compares result using regular expression or mask sorted in file.Assert::count($count, $value)- Reports an error if number of items in $value is not $count.Assert::with($objectOrClass, $closure)- Executes function that can access private and protected members of given object via $this.

Tips and features
Running unit tests manually is annoying, so let Nette Tester to watch your folder with code and automatically re-run tests whenever code is changed:
Running tests in parallel is very much faster and Nette Tester uses 8 threads as default. If you wish to run the tests in series use:
How do you find code that is not yet tested? Use Code-Coverage Analysis. This feature
requires you have installed Xdebug or PCOV
extension, or you are using PHPDBG SAPI. This will generate nice HTML report in coverage.html.
We can load Nette Tester using Composer's autoloader. In this case it is important to setup Nette Tester environment:
We can also test HTML pages. Let the template engine generate
HTML code or download existing page to $html variable. We will check whether
the page contains form fields for username and password. The syntax is the
same as the CSS selectors:

Running tests
The command-line test runner can be invoked through the tester command (or php tester.php). Take a look
at the command-line options:
