Cypress Chainable Commands (analyze)

`cy.axeAnalyze()`

This chainable command injects axe into all pages and iframes and then runs axe on the page.

Parameter	Type	Default Value	Description
name (optional)	String	undefined	Sets the identifier for this scan result stored in the report. Defaults to a timestamp if not provided.
context (optional)	axe.ElementContext	undefined	Defines the scope of the analysis--the part of the DOM that you would like to analyze. This will typically be the document or a specific selector such as class name, ID, selector, etc.
options (optional)	axe.RunOptions	undefined	Set of options passed into rules or checks, temporarily modifying them. This contrasts with `axe.configure`, which is more permanent.
log (optional)	Boolean	false	Returns output to stdout with the number of elements that are not accessible and violation impacts as a table.

`cy.isAxeClean()`

This chainable command is an assertion that the page has no accessibility violations.

Parameters:

Parameter	Type	Default Value	Description
context (optional)	axe.ElementContext	undefined	Defines the scope of the analysis--the part of the DOM that you would like to analyze. This will typically be the document or a specific selector such as class name, ID, selector, etc.
options (optional)	axe.RunOptions	undefined	Set of options passed into rules or checks, temporarily modifying them. This contrasts with `axe.configure`, which is more permanent.

Cypress Chainable Commands (configuration)

Integrate Axe DevTools for Web with Cypress using custom Cypress chainable commands to configure analyzed results.

`cy.setAxeSource()`

This chainable command sets the version of axe-core.

Parameter	Type	Default Value	Description
File path (required)	String	null	Path relative to the root of the project that should include `axe.source` or minified version of axe-core.

`cy.setAxeCustom()`

This chainable command allows the use of custom rulesets.

Axe DevTools for Web Cypress will also implicitly read axe-ruleset.json when placed in the root level of the project or will also use custom ruleset files when the AXE_RULESET_PATH environment variable is set.

Parameter	Type	Default Value	Description
File path (required)	String	null	Path relative to the root of the project that should include checks and rules

`cy.setAxeRuleset()`

This chainable command allows users to run rules per tags, similar to configuring axe.run().

Parameter	Type	Default Value	Description
ruleset (required)	'508', 'en301549', 'rgaav4', 'ttv5', 'wcag2', 'wcag2.1', 'wcag2.2', 'wcag2aaa', 'wcag2.1aaa', 'wcag2.2aaa'	'wcag2.1'	Array of tags that this rule is assigned.

`cy.setAxeReportName()`

This chainable command allows users to set the name of the report file.

Parameter	Type	Default Value	Description
reportName (required)	String	@axe-devtools-cypress	Name of the report file.

`cy.getAxeResults()`

This chainable command allows users to utilize the results after running cy.axeAnalyze().

Responses from getAxeResults() returns the data shape axe.AxeResults.

Example:

after(() => {
  cy.axeAnalyze();
  cy.getAxeResults().then(data => {
    cy.writeFile('./results.json', data)
  })
})

`cy.getUniversalResults()`

This chainable command returns the results of the most recent cy.axeAnalyze() call in the Axe Universal Format. Returns null if no analysis has been run yet.

Example:

after(() => {
  cy.axeAnalyze();
  cy.getUniversalResults().then(data => {
    cy.writeFile('./results-universal.json', data)
  })
})
