If the project was imported to the IDE before adding new plugin, re-generate the configuration files for the used IDE and then refresh the project in the used IDE.

Steps

Validate accessibility

Then I test accessibility:$options

$options - The accessibility validation options. Where:
- standard - The accessibility stanadard to verify against. One of WCAG2A, WCAG2AA, WCAG2AAA, Section 508
- level - The violation level used to check. One of:
  - ERROR - only errors will be validated,
  - WARNING - error and warning will be validated,
  - NOTICE - all the levels will be valiadted.
- locators - The comma-separated locators of elements to verify
- elementsToIgnore - The comma-separated locators of elements to ignore
- violationsToIgnore - The violations codes which should be ignored
- violationsToCheck - The violations codes which should be checked

If violation code will be set as checked and ignored then it will be checked and not ignored

The step based on the contextual approach and when it’s necessary it could be used to validate the accessibility of the context element only.

Example 2. Check accessibility

Given I am on page with URL `https://vividus-test-site.onrender.com/`
When I change context to element located by `xpath(//body)`
Then I test accessibility:
|standard|level |elementsToIgnore                                 |elementsToCheck|violationsToIgnore                                                                     |
|WCAG2AAA|NOTICE|By.id(ignore), By.cssSelector(#errors > h1 > img)|               |WCAG2AAA.Principle1.Guideline1_3.1_3_1.H42.2,WCAG2AAA.Principle2.Guideline2_4.2_4_9.H30|
|WCAG2AAA|NOTICE|By.xpath(//*)                                    |               |                                                                                       |
