First 20 minutes

General Eggplant Functional app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in Eggplant Functional application development, including their experience with various programming languages, databases, and their approach to designing scalable and maintainable systems.

How would you explain the purpose of Eggplant Functional?
Eggplant Functional is a test automation tool used for testing software applications across multiple platforms. It uses image recognition and text recognition to interact with applications as a user would.
Describe the difference between image-based testing and object-based testing in Eggplant Functional.
Image-based testing identifies and interacts with elements on the screen using image recognition, while object-based testing identifies elements using properties of the objects. Eggplant Functional primarily uses image-based testing.
What are the key components of Eggplant Functional's architecture?
The key components include the Eggplant Functional application, the System Under Test (SUT), and the VNC server. The VNC server is installed on the SUT, and Eggplant Functional connects to the SUT through the VNC server.
How would you use Eggplant Functional to automate a test case?
You would use SenseTalk, Eggplant Functional's scripting language, to write a script that replicates the steps of the test case. The script would use image recognition to interact with the application.
What are the prerequisites for running an Eggplant Functional test?
The prerequisites include having the Eggplant Functional application installed, having the SUT set up with a VNC server, and having a script written in SenseTalk.

Next 20 minutes

Specific Eggplant Functional development questions

The next 20 minutes of the interview should focus on the candidate's expertise with specific backend frameworks, their understanding of RESTful APIs, and their experience in handling data storage and retrieval efficiently.

How would you handle dynamic elements in Eggplant Functional?
You could use techniques like image tolerances, text recognition, or dynamic image generation to handle dynamic elements. These techniques allow Eggplant Functional to interact with elements that may change over time.
What are the advantages of using Eggplant Functional for test automation?
Advantages include the ability to test across multiple platforms, the ability to test applications as a user would, and the ability to handle dynamic elements.
Describe the difference between the Run window and the Suite window in Eggplant Functional.
The Run window is where you execute scripts, while the Suite window is where you manage your scripts, images, and other resources.
How would you debug a script in Eggplant Functional?
Eggplant Functional provides several tools for debugging, including breakpoints, stepping, and variable watchers. You would use these tools to step through your script and identify where it's going wrong.
What are the steps to connect Eggplant Functional to a SUT?
You would need to install a VNC server on the SUT, then in Eggplant Functional, you would enter the IP address and port number of the VNC server to connect.

Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with Eggplant Functional.

What does the following Eggplant Functional script do?
Click "LoginButton"
This script performs a mouse click on the screen element identified as 'LoginButton'.
What will be the output of the following Eggplant Functional script?
put the result into Result
put Result's stdout
This script captures the result of the last executed command into a variable named 'Result', then outputs the standard output of that result.
What does the following Eggplant Functional script do?
put (1,2,3) into myArray
put item 2 of myArray
This script creates an array with the elements 1, 2, and 3, then retrieves the second item of the array, which is 2.
What does the following Eggplant Functional script do?
start using "MySuite"
RunWithNewResults "MyScript"
This script loads a suite named 'MySuite' into memory, then runs a script named 'MyScript' within that suite in a new results environment, isolating it from any other scripts that are running at the same time.

Wrap-up questions

Final candidate for Eggplant Functional Developer role questions

The final few questions should evaluate the candidate's teamwork, communication, and problem-solving skills. Additionally, assess their knowledge of microservices architecture, serverless computing, and how they handle Eggplant Functional application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

How would you use the Text Image Generation feature in Eggplant Functional?
You would use Text Image Generation to interact with text on the screen, especially when the text is dynamic or not easily captured as an image. You can specify the properties of the text, such as the font, size, and color.
Describe the difference between the WaitFor command and the ImageFound function in Eggplant Functional.
The WaitFor command waits for a specified image to appear on the screen before continuing. The ImageFound function checks if an image is on the screen and returns a boolean value.
How would you handle synchronization issues in Eggplant Functional?
You could use commands like WaitFor and Wait to ensure that Eggplant Functional waits for certain conditions to be met before proceeding.
