ngMocks.findTemplateRef

Returns the first found TemplateRef which belongs to the current element or its any child. If the element is not specified, then the current fixture is used.

  • ngMocks.findTemplateRef( fixture?, directive, notFoundValue? )
  • ngMocks.findTemplateRef( debugElement?, id, notFoundValue? )
  • ngMocks.findTemplateRef( debugElement?, [attribute, value?], notFoundValue? )

or simply with selectors which are supported by ngMocks.find.

  • ngMocks.findTemplateRef( cssSelector?, [attribute, value?], notFoundValue? )

Directive#

Assume, that a template has the next code.

<ng-template my-directive-1></ng-template><span *my-directive-2></span>

Then we can find ng-template like that:

const tpl1 = ngMocks.findTemplateRef(MyDirective1);const tpl2 = ngMocks.findTemplateRef(MyDirective2);

Id#

Assume, that a template has the next code.

<ng-template #header></ng-template><ng-template #footer></ng-template>

Then we can find ng-template like that:

const tplHeader = ngMocks.findTemplateRef('header');const tplFooter = ngMocks.findTemplateRef('footer');

Attribute selector#

Assume, that a template has the next code.

<ng-template mat-row></ng-template><ng-template mat-cell></ng-template>

Then we can find ng-template like that:

const tplRow = ngMocks.findTemplateRef(['mat-row']);const tplCell = ngMocks.findTemplateRef(['mat-cell']);
important

Pay attention that a tuple is used, otherwise it will be id look up.

Input with value#

Assume, that a template has the next code.

<ng-template myTpl="header"></ng-template><ng-template [myTpl]="property"></ng-template>

Then we can find ng-template like that:

const tplHeader = ngMocks.findTemplateRef(['myTpl', 'header']);const tplInput = ngMocks.findTemplateRef(['myTpl', property]);
important

Pay attention that property is a variable.
