# Assertions for Web Tests

Add assertions to Endtest Web Tests: assert element presence, text, attributes, URL, accessibility, and natural-language conditions with AI Assertions.

Part of the Endtest documentation (Web Tests). Canonical URL: https://endtest.io/docs/web-tests/assertions-for-web-tests

## Introduction

We need assertions in order to know if our test execution was successful or not.

If we do not add assertions in our test cases, the values for `Passed` and `Failed` will be zero.

A test case can have more than one assertion.

## Solution

Assertions can be added by using the `Add Assertion` action.

You can choose from the following types of assertions:

| Assertion Type                     | Description                                                                         |
