Selecting options from Mat-select using cypress

Question

I have Mat-select dropdown as follows

<mat-form-field>
   <mat-label>Gender</mat-label>
      <mat-select id="gender" required formControlName="gender">
         <mat-option id="Male" value="male"> Male </mat-option>
         <mat-option value="female"> Female </mat-option>
      </mat-select>
 </mat-form-field>

I'm trying to use Cypress to select male or female from the field.

cy.get('mat-select').click().select('Male')

With the above code I get the following error:

CypressError: cy.select() can only be called on a <select>. Your subject is a: <mat-select>

I need some help in fixing this, thank you.

The code that worked for me.

cy.get('#gender').click().then(() => {
            cy.get('#male').click()
        })

Answer 1

打开 mat-select 的 mat-option 对话框并选择包含“Apple Inc.”的字段。

cy.get('mat-select[formControlName=companyName]').click().get('mat-option').contains('Apple Inc.').click();

Answer 2

Basically what I did was to simulate the Dropdown opening and then sumulate another click for item selection:

 // simulate click event on the drop down cy.get('mat-select').first() .click(); // opens the drop down // simulate click event on the drop down item (mat-option) cy.get('.mat-option-text span') .contains('Your MatItem Text') .then(option => { option[0].click(); // this is jquery click() not cypress click() });

First, click on select for openning the overlay, then click on your option based on your option text content:

cy.get('mat-select[formcontrolname="departament"]').click();
cy.get('mat-option').contains('Lima').click();

My option text was Lima(+001) . When I queried .contains('Lima') I got 'AssertionError'. But when I query .contains('Lima') or .contains('001') element is found. It's seems to me that only supports alphanumeric (I didn't go in deep).

首先，选择打开叠加层，然后根据您的选项文本内容选择您的选项并使用should()来验证是否选择了确切的选项：

 cy.get('mat-select').select('Male').should('have.value','male');

Just for other people still strugling with this/similar issue, even after trying the solutions presented here.

Your problem might also be that you are using a within block. Therefore mat-select items cannot be reached after clicking on the mat-option . So either take this part out of the within block or use the {withinSubject:null} option when getting the mat-select item.

cy.get("mat-select[formControlName*='language']").click();
cy.get('mat-option', {withinSubject:null}).contains('English').click();

 cy.get('div[class="cdk-overlay-container"]').then(($container) => {
    if ($container.find("div[class='cdk-overlay-connected-position-bounding-box']").length > 0) {
      cy.get("div[class='cdk-overlay-connected-position-bounding-box']").each(($el) => {
        $el.remove();
      });
    }
    if ($container.find("div[class^='cdk-overlay-backdrop']").length > 0) {
      cy.get("div[class^='cdk-overlay-backdrop']").each(($el) => {
        $el.remove();
      });
    }
  });
