Step 1. To launch the selenium IDE, open Firefox browser and select Tools > Selenium IDE

Step 2. It opens with an empty script-editing window and a menu for loading or creating new test cases.

Step 3. Find below few of the IDE user interface options

Menu Bar

• File Menu – The file menu has options for test case and test suite. Using these you can add a new test case, open a test case, save a test case and export test case in a language of your choice.
• Edit Menu – The edit menu allows copy, paste, delete, undo and select all operations for editing the commands in your test case.
• Options Menu – The options menu allows the changing of settings. You can set the timeout value for certain commands, add user-defined user extensions to the base set of Selenium commands and specify the format (language) used when saving your test cases.
• Help Menu – The help menu is the standard Firefox help menu; only one item on this menu – UI Element Documentation pertains to Selenium IDE.

Tool Bar

The toolbar contains buttons for controlling the execution of your test  cases, including a step feature for debugging your test cases.

• Speed Control – This helps in controlling the speed of the test case runs.
• Run All – Runs the entire test suit when a suit with multiple test cases is loaded.
• Run – Runs the currently selected test. When only a single test is loaded this button and the Run All button have same effect.
• Pause/Resume – Allows stopping and re-starting of a running test case.
• Step – Allows you to “step” through a test case by running it one command at a time. Use for debugging test cases.
• Apply Rollup Rules – This advanced feature allows repetitive sequences of Selenium to be grouped into a single action. Detailed documentation of rollup rules can be found in the UI Element Documentation on the Help Menu.
• Record – Records the user’s browser actions.
