14 Cypress Assertions - biswajitsundara/Cypress GitHub Wiki
Cypress uses Chai library for assertions. Below are some commonly used assertions.
Let's say we are validating the number of rows in a table, or number of items under a list.
cy.get('li').should('have.length',3);
If we want to validate if the element has the text
cy.get('h1.logo-font').should('have.text','conduit');
We want to check the element is visible before performing the click operation.
cy.get('.btn').contains('Sign in').should('be.visible').click();
