- Execution controls: Gives buttons for working assessments, pausing assessments, stepping by way of assessments, and controlling execution pace.
Recording Your First Check Case
Now that you’ve got Selenium IDE put in and working, let’s file your first take a look at case.
Beginning a New Undertaking and Check Case
If you open Selenium IDE, you will be prompted to create a brand new challenge or open an current one. Select “Create a brand new challenge” and provides your challenge a descriptive identify. After creating the challenge, you will be prompted to create a brand new take a look at case inside that challenge. Once more, select a transparent and descriptive identify in your take a look at case.
Recording Actions
As soon as you’ve got created a brand new take a look at case, Selenium IDE will begin recording your actions within the browser. As you navigate to a web site, click on buttons, enter textual content, and carry out different actions, the IDE robotically data these actions as instructions in your take a look at case. It’s like having a digital recorder following your each transfer inside the browser.
Stopping the Recording

Instance Situation:
Let’s stroll by way of an instance state of affairs: testing the login performance of a demo web site.
- Open Selenium IDE.
- Create a brand new challenge named “DemoWebsiteTests.”

- Navigate to a demo web site with a login type (many can be found on-line – seek for “demo login web site”).
- Enter a username within the username area.
- Enter a password within the password area.
- Click on the “Login” button.
- Cease the recording.
Selenium IDE will now have recorded all these actions as instructions in your “LoginTest” take a look at case.
Taking part in Again and Analyzing Check Outcomes
After getting recorded your take a look at case, you’ll be able to play it again to confirm its performance.

To run your take a look at case, merely click on the “Run present take a look at” button within the Selenium IDE window. The IDE will robotically replay the recorded actions in your browser, simulating the steps you carried out throughout recording.
Decoding the Outcomes
Because the take a look at case runs, the Log panel in Selenium IDE will show the outcomes of every command. A inexperienced checkmark signifies that the command handed efficiently, whereas a purple “X” signifies that the command failed. Pay shut consideration to any error messages within the Log panel, as they will present priceless clues about the reason for the failure. The log offers element data like “command failed to seek out factor” or “factor textual content didn’t match.”
Debugging Failed Exams
If a take a look at case fails, you should use the “Step” button to stroll by way of the take a look at command by command. This lets you pinpoint the precise step the place the failure occurred. Look at the command, its goal, and its worth to establish the foundation explanation for the issue.

open,click on,kind,assertTitle). - Goal: The factor on which the motion ought to be carried out (e.g., a button, a textual content area, a hyperlink). This makes use of a locator technique.
- Worth: The worth for use within the motion (e.g., the textual content to enter in a textual content area, the anticipated title of the web page).
Selenium IDE makes use of locators to establish net parts. The commonest locator methods embody ID, identify, XPath, and CSS selector. Selecting the best locator technique is essential for creating dependable assessments. IDs are essentially the most secure, but when IDs are dynamic or absent, CSS selectors or XPath may be wanted.
Including and Modifying Instructions
You possibly can add new instructions to your take a look at case by clicking the “+” button within the command checklist and deciding on a command from the dropdown menu. You can even edit current instructions by clicking on the command within the checklist and modifying its goal or worth.
Including Assertions and Verifications
Assertions and verifications are important for verifying that your take a look at case is performing as anticipated. Assertions examine if a sure situation is true and cease the take a look at if the situation is fake. Verifications, then again, examine if a situation is true however proceed the take a look at even when the situation is fake. Widespread assertions embody assertText (verifies the textual content of a component), assertElementPresent (verifies that a component is current on the web page), and assertTitle (verifies the title of the web page).
Utilizing Variables
Selenium IDE means that you can use variables to make your assessments extra versatile. You possibly can declare variables utilizing the retailer command after which use them in different instructions by referencing them with ${variableName}. Variables are helpful for storing dynamic values, comparable to dates or instances.
Move Management (If/Else)
You should utilize if...else logic to regulate the circulate of your assessments. The if command checks a situation, and if the situation is true, the instructions inside the if block are executed. In any other case, the instructions inside the else block (if current) are executed. This lets you create assessments that may deal with totally different eventualities. The retailer command can be utilized to retailer the results of an expression to be used in an if assertion.
Exporting and Reusing Check Instances
Selenium IDE means that you can export your take a look at circumstances to varied programming languages, permitting you to combine them into bigger testing frameworks.
Exporting Exams to Completely different Languages
