在PHPUnit中测试表单输入

$formInput = $this->getMockBuilder(FormInput::class)
    ->setMethods(['getValue'])
    ->getMock();

$formInput->expects($this->once())
    ->method('getValue')
    ->willReturn('testValue');

$this->assertEquals('testValue', $formInput->getValue());

$formInput = $this->createMock(FormInput::class);

$formInput->method('getValue')
    ->willReturn('testValue');

$this->assertEquals('testValue', $formInput->getValue());

$formInput = $this->createPartialMock(FormInput::class, ['getValue']);

$formInput->method('getValue')
    ->willReturn('testValue');

$this->assertEquals('testValue', $formInput->getValue());

$formInput = $this->createStub(FormInput::class);

$formInput->method('getValue')
    ->willReturn('testValue');

$this->assertEquals('testValue', $formInput->getValue());
