Returns a found DebugElement which belongs to a component with the correctly typed componentInstance, or matches a css selector. If a root element or a fixture are not specified, then the current fixture is used.

  • ngMocks.find( fixture?, component, notFoundValue? )
  • ngMocks.find( fixture?, cssSelector, notFoundValue? )
  • ngMocks.find( debugElement?, component, notFoundValue? )
  • ngMocks.find( debugElement?, cssSelector, notFoundValue? )

Component class#

const element1 = ngMocks.find(Component1);const element2 = ngMocks.find(fixture, Component2);const element3 = ngMocks.find(fixture.debugElement, Component3);

CSS Selector#

const element1 = ngMocks.find('div.con1');const element2 = ngMocks.find(fixture, 'div.con2');const element3 = ngMocks.find(fixture.debugElement, 'div.con3');


cssSelector supports a tuple to generate an attribute css selector. The first value is the name of an attribute, the second value is optional and points to the desired value of the attribute.

const el1 = ngMocks.find(['data-key']);// the same asconst el2 = ngMocks.find('[data-key]');
el1 === el2; // true
const el1 = ngMocks.find(['data-key', 5]);// the same asconst el2 = ngMocks.find('[data-key="5"]');
el1 === el2; // true
