Opening Selenium IDE
As soon as put in, you may open Selenium IDE by clicking the Selenium IDE icon in your browser toolbar. The IDE will open in a brand new window, prepared so that you can create and handle your take a look at circumstances.
Preliminary IDE Interface Overview
The Selenium IDE interface consists of a number of key elements:
- Menu bar: Offers entry to numerous choices, corresponding to creating new tasks, opening present tasks, saving take a look at circumstances, and configuring settings.
- Command/Locator/Worth enter fields: Used to manually add or edit instructions in your take a look at circumstances.
- Log panel: Shows the outcomes of take a look at execution, together with move/fail standing, error messages, and debugging data.
- Take a look at Case/Suite panel: Lets you handle your take a look at circumstances and arrange them into take a look at suites.
- Execution controls: Offers buttons for operating assessments, pausing assessments, stepping by way of assessments, and controlling execution velocity.
Recording Your First Take a look at Case
Now that you’ve got Selenium IDE put in and operating, let’s document your first take a look at case.
Beginning a New Mission and Take a look at Case
While you open Selenium IDE, you will be prompted to create a brand new mission or open an present one. Select “Create a brand new mission” and provides your mission a descriptive title. After creating the mission, you will be prompted to create a brand new take a look at case inside that mission. Once more, select a transparent and descriptive title to 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 an internet site, click on buttons, enter textual content, and carry out different actions, the IDE mechanically data these actions as instructions in your take a look at case. It’s like having a digital recorder following your each transfer throughout the browser.
Stopping the Recording
While you’ve accomplished the actions you wish to document to your take a look at case, click on the “Cease recording” button within the Selenium IDE window. It will finish the recording and save your actions as a sequence of instructions.
Instance Situation:
Let’s stroll by way of an instance situation: testing the login performance of a demo web site.
- Open Selenium IDE.
- Create a brand new mission named “DemoWebsiteTests.”
- Create a brand new take a look at case named “LoginTest.”
- 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.
Enjoying Again and Analyzing Take a look at Outcomes
After you have recorded your take a look at case, you may play it again to confirm its performance.
Operating a Take a look at Case
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 mechanically 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 crimson “X” signifies that the command failed. Pay shut consideration to any error messages within the Log panel, as they’ll present precious clues about the reason for the failure. The log supplies element information like “command failed to seek out factor” or “factor textual content didn’t match.”
Debugging Failed Assessments
If a take a look at case fails, you need to 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. Study the command, its goal, and its worth to establish the basis reason for the issue. Widespread points embrace incorrect locators, incorrect values, or adjustments to the web site’s construction.
Enhancing and Customizing Take a look at Instances
Selenium IDE lets you edit and customise your take a look at circumstances to make them extra sturdy and versatile.
Understanding Instructions, Targets, and Values
Every command in Selenium IDE consists of three components:
- Command: The motion to be carried out (e.g.,
open,click on,kind,assertTitle). - Goal: The factor on which the motion needs 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 components. The commonest locator methods embrace ID, title, XPath, and CSS selector. Choosing the proper locator technique is essential for creating dependable assessments. IDs are essentially the most steady, 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 choosing a command from the dropdown menu. It’s also possible to edit present 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, alternatively, examine if a situation is true however proceed the take a look at even when the situation is fake. Widespread assertions embrace 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 lets you 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, corresponding to dates or occasions.
Move Management (If/Else)
You need to use if...else logic to regulate the move of your assessments. The if command checks a situation, and if the situation is true, the instructions throughout the if block are executed. In any other case, the instructions throughout the else block (if current) are executed. This lets you create assessments that may deal with completely different situations. The retailer command can be utilized to retailer the results of an expression to be used in an if assertion.
Exporting and Reusing Take a look at Instances
Selenium IDE lets you export your take a look at circumstances to numerous programming languages, permitting you to combine them into bigger testing frameworks.
Exporting Assessments to Completely different Languages
Selenium IDE helps exporting take a look at circumstances to languages like Java, Python, C#, and Ruby.
