Common Mistakes

• Make sure all words are spelled correctly (if applicable).

• Do not use any inline styles in the HTML component in files.
• Make sure everything is aligned correctly.
• Please avoid making global variables.

• Remove all test code within the working sections when ready to push to master.

Responsiveness

For all below check the following breakpoints for Vue apps

Devices	Code	Screen sizes
Extra Small	xs	< 600px
Small	sm	600px > < 960px
Medium	md	960px > < 1264px
Large	lg	1264px > < 1904px
Extra Large	xl	> 1904px

• Check for bad word breaks within each breakpoint.
• Check to see if components are misaligned or have bad spacing, padding, or margin.
• Check to see if components overflow to either side of the viewport.
• Check if there are any weird visual glitches at different breakpoints.

Other items to look out for

• Make sure new API calls use the correct HTTP verb and when working with JSON make sure it is validated.
• With GETs, make sure that text/html return type is avoided and application/json is used when dealing with json data.
• Avoid transmission of confidential data in URL parameters and unnecessary parameters.
• Make sure all API calls are within a try catch block with appropriate error handling.
• If dealing with forms, make sure the form has input validation.
• Avoid logging confidential information.
• Make sure no-cache is on confidential web pages.
• Make sure rel="noopener noreferrer" is on any link that opens to a new tab.
• For browser performance, use .webp images instead of .png, .jpg, .jpeg, etc.

• Make sure any new download buttons (that don't use DownloadButton.vue) have the attribute data-cy="download".
• Make sure new pages / paths within router.js are added to the links.js test suite.
• Add a new test case within downloads.js if you're adding the first download button to any page.
• Reuse existing custom commands if they serve the purpose of your test.
• Create a new custom command for any duplicate code / test that can be globally reused.
• Create a local function for duplicate code that can be reused within your test spec.
