This article mainly introduces "how to use TestNG framework to create Selenium script". In daily operation, I believe many people have doubts about how to use TestNG framework to create Selenium script. The editor has consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubt of "how to use TestNG framework to create Selenium script". Next, please follow the editor to study!

I. characteristics of testng

Support for comments

Support for parameterization

Advanced execution methods that do not require the creation of test suites

Data-driven testing based on the data provided by the data provider

Allow users to set execution priorities for test methods

Provide a secure environment when executing multithreading

Support the integration of various tools and plug-ins, such as build tools (Ant, Maven, etc.), integrated development environment (Eclipse).

It provides an effective method for users to generate reports using ReportNG.

Comparison of TestNG and Junit:

TestNG has many advantages over JUnit:

Advanced and simple comments

You can set the execution mode

Concurrent execution of test scripts

You can set test case dependencies

In both TestNG and JUnit, comments are preceded by an "@" symbol.

II. Install TestNG in Eclipse

Follow these steps to download and install TestNG on eclipse

Step 1: start eclipse IDE- > Click the help option on the menu bar-> Select "Eclipse Marketplace.." in the drop-down box Option

Step 2 enter the keyword "TestNG" in the search box and click the go button

Step 3: when the go button is clicked, the matching search results are displayed. Click the install button to install "TestNG".

After downloading step 4, there will be a pop-up confirmation window. Click confirm to confirm.

Step 5 next, the application will pop up the accept license box and click the "Finish" button

Step 6 to start the installation, you can see the installation progress bar

Restart eclipse

After reboot, click "Preferences" under the "Window" option on the menu bar to verify the installation of TestNG. Please refer to the following figure

III. Create a TestNG project example

Step 1 Click File- > new- > java Project in the menu bar

Step 2 enter the project name such as "DemoTestNG", click the "Next" button, and click the "Finish" button, so that the java project is created successfully

Step 3: import the TestNG directory into the newly created java project, click the "Libraries" tab under Build Path, and click "Add library".

Step 4 in the pop-up dialog box, select TestNG, click the "Next" button, and click the "finish" button.

Now TestNG has been added to Java project, as shown in the following figure

Add all downloaded Selenium libraries and jar to the build path of the project.

IV. Create a TestNG class

Create a sample script

Step 1 expand the "Demo TestNG" project, select the "src" folder, and right-click the "src" package to navigate to New-> Other.

Step 2: open the TestNG option, select the TestNG option, and click the next option.

Step 3 specify the source folder, package name, and TestNG class name, and then click the Finish button.

The TestNG class will be created using the default mode

Scene:

Launch the browser and open "Gmail.com".

Verify the page title and print the verification results.

Enter your user name and password.

Click the login button.

Close the web browser.

Code interpretation:

1) @ Test is one of the TestNG comments. This comment lets the program know that the method labeled @ Test is a test method. To be able to use different TestNG annotations, we need to import the package "import org.testng.annotations.*".

2) the main () method is not required to create a test script using TestNG. The execution of the program is completed on the basis of comments.

3) in the statement, we use the Assert class when comparing the expected value with the actual value. The Assert class is used to perform various validations. In order to be able to use different classes, we need to import "import org.testng.Assert".

V. Execute the TestNG script

Right-click anywhere in the code area, or right-click on the java package to select the "Run As" option, and click "TestNG Test" to run

TestNG results are displayed in two windows

Console window

TestNG result window

VI. HTML report

TestNG has the powerful ability to generate user-readable and understandable HTML reports. These reports can be viewed in any browser or using Eclipse's built-in browser support.

Build steps:

Step 1: execute the newly created TestNG class. Right-click the project that contains the TestNG class and select the "Refresh" option to refresh

Step 2: generate a folder called "test-output" at the "src" folder level, expand the "test-output" folder, open "email-report" in an Eclipse browser, and the HTML file displays the results of the most recent execution.

Step 3:HTML report is opened in the eclipse environment, see the following figure

Seven. Set the priority in TestNG

Example:

Eight. Code check

If the test script consists of multiple test methods, you can use the TestNG annotation "@ Test" and set the execution priority and order by setting the value of the "priority" parameter.

In the code snippet above, all methods are annotated with @ Test, with priority set to 0, 1, and 2. Therefore, the execution order of the test method is:

Method1

Method2

Method3

Support annotations

Many comments are available in TestNG and JUnit. The small difference is that TestNG provides some more advanced comments for JUnit.

9. Comments on testng

The following are the most useful comments in TestNG:

Ten. Summary
