tests:
- text: The <code>ResetPassword</code> component should return a single <code>div</code> element.
testString: assert((function() { const mockedComponent = Enzyme.mount(React.createElement(ResetPassword)); return mockedComponent.children().type() === 'div'; })(), 'The <code>ResetPassword</code> component should return a single <code>div</code> element.');
- text: The fourth child of <code>ResetPassword</code> should be the <code>ReturnTempPassword</code> component.
testString: assert((function() { const mockedComponent = Enzyme.mount(React.createElement(ResetPassword)); return mockedComponent.children().childAt(3).name() === 'ReturnTempPassword'; })(), 'The fourth child of <code>ResetPassword</code> should be the <code>ReturnTempPassword</code> component.');
- text: The <code>ReturnTempPassword</code> component should have a prop called <code>tempPassword</code>.
testString: assert((function() { const mockedComponent = Enzyme.mount(React.createElement(ResetPassword)); return mockedComponent.find('ReturnTempPassword').props().tempPassword; })(), 'The <code>ReturnTempPassword</code> component should have a prop called <code>tempPassword</code>.');
- text: The <code>tempPassword</code> prop of <code>ReturnTempPassword</code> should be equal to a string of at least <code>8</code> characters.
testString: assert((function() { const mockedComponent = Enzyme.mount(React.createElement(ResetPassword)); const temp = mockedComponent.find('ReturnTempPassword').props().tempPassword; return typeof temp === 'string' && temp.length >= 8; })(), 'The <code>tempPassword</code> prop of <code>ReturnTempPassword</code> should be equal to a string of at least <code>8</code> characters.');
- text: The <code>ReturnTempPassword</code> component should display the password you create as the <code>tempPassword</code> prop within <code>strong</code> tags.
testString: assert((function() { const mockedComponent = Enzyme.mount(React.createElement(ResetPassword)); return mockedComponent.find('strong').text() === mockedComponent.find('ReturnTempPassword').props().tempPassword; })(), 'The <code>ReturnTempPassword</code> component should display the password you create as the <code>tempPassword</code> prop within <code>strong</code> tags.');
