protractor e2e typescript for mat-selection-list checkboxes - select all

Question

How do I check all checkboxes in this page using protractor ?

I tried to access the elements this way but doesn't seem to be working.

select = element(by.cssContainingText('mat-card-title', 'Classifications'))
    .all(by.css('mat-pseudo-checkbox'));

Your approach does not work because mat-card-title does not have any child elements. When chaining element() calls, it always only searches for child elements.

For selecting the correct elements, we have to take the parent mat-card and filter it by by.cssContainingText().

After filtering we have to locate the mat-pseudo-checkbox elements and send a click to these underlying elements.

That can be achieved as follows:

// select correct element group
let wrapper = element.all(by.tagName('mat-card'))
  .filter(el => el.element(by.tagName('mat-card-title'))
  .getText()
  .then(text => {
    console.log('looking if\'', text, '\'contains Classifications');
    return text.indexOf('Classifications') > -1;
  }));

   wrapper.all(by.css('mat-card-content mat-selection-list mat-list-option .mat-list-item-content .mat-list-text'))
  .each(async el => await el.click());
