That’s really informative, thanks for that 
So, I have a free trial of a Google Gemini Advanced account. As some of you will know, Google’s pet AI has a bit of a reputation for being rather politically correct. I came up with a set of rather evil requirements. You can see the results here:

It seems to me that the IDE plug-ins can work better, because they can look at your actual code and have more context for generating useful test data. Maybe a naive thought on my part, but I do see good test data coming out of IDE Plug-in AI assistants like Cody and Tabnines.

That was very interesting. I was as equally pleased to see it kept noting the ethical consequences as I am wondering how easy it may be to gas light it into disregarding them.
I should add to the above that the example is in no way indicative of how I use AI, For one thing, I’m terrified of inadvertently handing over proprietary or confidential information to any of the FAANGSs. Now, I’m a big user of Java and Cucumber in my work. Recently, I found myself having to work with Python and Behave. I was using AI to solve this kind of problem:
Much of what I do with AI is based on getting it to demonstrate principles of things to me. I know how to do a thing in Java, but not in Python. Reading chapter and verse on something that is going to be conceptually very similar is not, IMHO, productive use of my time.

Agreed. I was impressed - it got the balance right. I suspect it would outright refuse to design the machinery, automation framework and glue/steps code though.

My experience of Gemini vs Chat GPT is that Gemini gives comprehensive answers, often providing further elaboration or prompting you back for other things you could ask, while Chat GPT is more likely to produce something that works without needing correction.
Both require a degree of self-awareness. I did not understand parts of some Go code I asked Gemini to produce for me, which meant I was in the wrong place (meaning Udemy or Pluralsight would both be more appropriate)!

Hello everyone!
For this very interesting task I chose to use ChatGPT as tool for test data generation. I assigned the role of QA engineer to it and asked for a json with test data for the most basic test cases in an e-commerce, an ERP and a PLM application.
I evaluated the results as good enough for the generic prompt I gave to it, and also when I re-asked for test data for some different test cases from the previous ones its response was satisfied, too.
Although, chat generates good ideas but not novel ones.
The conclusion for me is that the prompt definitely plays a crucial role in user’s interaction with an LLM, but even with a good one the results may be not as usefull as expected, especially in very specific test cases.

Hi,
for this task, I have chosen not so much test data generation, but instead test data manipulation.
This is something I needed to do in real life as a part of analyzing the data on the site.
There was a dropdown with the list of countries and when you select it then the countries that have multiple regions have another dropdown displayed with the list of regions.
The issue was that some countries had a region dropdown displayed even though it had just 1 region. In this case, information was supposed to be displayed differently since there is no sense in selecting just 1 option from the region dropdown. Instead the information should display directly info for that region.
My task was to list all the countries for which the region dropdown contained only 1 region → problematic ones.
I wanted to start by listing all the countries from the country dropdown and putting it into the table.
I pasted a HTML snippet to prompt and asked it to count the countries and list them into the table.
For some reason, gpt has issues with it and was not able to process it, it kept saying that the HTML is not complete (even though in my opinion it was).
Here is the chat so please advice if you have any ideas how to achieve my goal → process the test data from HTML into simple table with the counter column.
Thanks!
MJ 
Again community to the rescue - Eskcanta strikes again in the OpenAI discord - my friend in need and a friend indeed.
The issue is that the pasted HTML snippet was too big for it to process in its python tool.
So the trick is to put it into a file and ask to generate a file a again with the extracted countries in the complete list.

I gave ChatGPT the definition for a database field from a specification.
ME:
Please create test data for a web application field called “RI” that accepts 7 or 8 characters - CCCDDAA or CCCDDAAA - following below rule:
CCC = Location identifier = 3 alpha ‘aaa’, numeric characters are not allowed DD = Office Function Designator = 2 alpha/numeric characters allowed formats: ‘aa’ alpha + alpha ‘an’ alpha + numeric ‘na’ numeric + alpha ‘nn’ numeric + numeric
AA[A] = Organization Code = 2 or 3 alpha/numeric characters allowed formats: ‘aa’ alpha + alpha ‘an’ alpha + numeric ‘na’ numeric + alpha ‘aaa’ alpha + alpha + alpha ‘naa’ numeric + alpha + alpha ‘ana’ alpha + numeric + alpha ‘nna’ numeric + numeric + alpha
ChatGPT
Based on the provided rules, here are some example test data for the “RI” field:
- Valid examples (7 characters):
- ABC12XY: Location identifier (ABC), Office Function Designator (12), Organization Code (XY)
- XYZ3Z9F: Location identifier (XYZ), Office Function Designator (3Z), Organization Code (9F)
- Valid examples (8 characters):
- DEF34XYZ: Location identifier (DEF), Office Function Designator (34), Organization Code (XYZ)
- MNO5Z9FU: Location identifier (MNO), Office Function Designator (5Z), Organization Code (9FU)
- Invalid examples:
- 12345XY: Numeric characters are not allowed in the Location identifier part.
- ABC123XY: Too many characters in the Office Function Designator part.
- XYZ34Z9F: Invalid combination of characters in the Office Function Designator part.
- PQR56789: Too many characters in the Organization Code part.
These examples cover various scenarios to test the validation of the “RI” field in your web application.
The problem is that it looked at each of the 3 parts separately instead of the combination of the characters which resulted in invalid suggestions that are actually valid.

4. Assessment of Generated Data
Compared to ChatGPT3.5, the data generated by ChatGPT4 is somewhat more aligned with expectations, but it tends to be overly simplistic. For instance, in the scenario of email account registration, the data lacks complexity and does not utilize methods like equivalence classes, boundary values, scenario design, decision tables, cause-and-effect graphs, orthogonal arrays, error guessing, etc., for test case design.
I further prompted ChatGPT to supplement more test data specifically for the email account and password registration scenario:
Generate additional test data for the email account and password registration scenario.
The results from ChatGPT in response to this query better matched the typical testing scenarios we require, as shown below:

5. Share Your Findings
In my daily work scenarios where I need to generate test data, I communicate extensively with ChatGPT through prompts and additional context. Initially, I use prompts and business scenarios to have ChatGPT generate an initial version of the test data. Subsequently, I iterate through multiple rounds of context and rule supplementation based on the initial results to obtain usable data. The final step involves manual review and filtering before utilizing the data for work.
Overall, generating desired test data through a simple step with ChatGPT appears challenging at the moment. However, it proves effective in opening up ideas and exploring new business scenarios. I am continually exploring and learning prompt strategies to make test data generation with ChatGPT more straightforward. Hopefully, with better prompts in the future, the process will become more streamlined.

Good skills, Nice spot.
And, yikes! That’s one of my biggest fears with prompt results.

Feel free to modify or expand this data as needed for your application.
Findings: 
a.The data problem you were trying to solve and how well you think the tool performed.
I didn’t have a data problem, I was just checking what it does
b.Your perceptions about what was positive and negative about the tool and the data generated.
data are legit for this example but it just ignored my request to fill in 50 rows each, will try with a smaller number and see what will happen
** c.How the generated data might be improved.**
for this example, it’s ok. but I was playing around with login feature data and since I didn’t exactly specify the constraints for valid inputs I saw that valid and invalid data for username, email, and password were practically the same
** d.How might the tool help with your day-to-day testing activities?**
with the right prompt, this will make test data generation a much easier task

I wanted to see if chatgpt was a good way to generate data for my database. I wanted data to enroll children into kindergarten. However it chastised me for it!
“Creating fictitious data for such purposes is often discouraged due to privacy concerns. However, I can provide you with a hypothetical sample format that you can use to generate random data using appropriate tools or software. Please ensure that any data generated or used adheres to privacy and ethical standards.”
It then also provided a data example such as I proposed in my prompt and then suggested that I use a different tool.
"You can use tools like Microsoft Excel, Google Sheets, or programming languages like Python with libraries such as pandas to generate random data based on this format. Ensure that any data generated is purely fictional and doesn’t infringe on anyone’s privacy rights.
If you need further assistance with generating random data using specific tools or languages, feel free to ask!"
I had better luck when I asked it to do one field at a time. It had no moral qualms about doing that!
PROMPT: Can you produce a list of 100 boy names?
CHATGPT: Certainly! Here’s a list of 100 random boy names:
[Randmom list starting with Liam and ending with Axel]
It also gave me a list of 100 last names and girl names.
I found that chatgpt was pretty good at making lists of random data, but it did not want to completely solve my complete problem in one prompt because of moral qualms.

Mockaroo
The tool supports a wide range of data types and provides options for generating realistic data, including names, addresses, phone numbers, and more. The tool also provides options to export the generated data in various formats, including CSV, JSON, SQL, and Excel.
I choose to continue with ChatGPT and also try Mockaroo in order to create realistic data for tests.
Find a Data Problem to solve: I create prompt to generate personal data of employees for HR database: first name, last name, email, phone, department. Mockaroo can generate large amount of data, can now generate more than 5000 records per file, and create realistic data very fast. Good point is that you can choose format of given data, SQL, Excel, JSON, XML, etc.:
The question is, if it is possible to create prompt with more specific query in addition to what is in the fields.
After that I generate prompt for the same data to ChatGPT and get two simples in XML format with suggestion to create the last data by myself 
:
After that I asked to generate 50 rows and got data, those was created good, but more slowly that with Mockaroo:

Hi
I’ve used ChatGPT. We talked in this way
You’re testing an application that accepts json file as input. Please generate various types of json files to test the functionality of the application
I got answers like this
Sure! Here are some example JSON files with various structures and data types that you can use to test your application:
- Basic JSON with key-value pairs:
jsonCopy code
{
"name": "John Doe",
"age": 30,
"city": "New York"
}
- JSON with nested objects:
jsonCopy code
{
"person": {
"name": "Jane Smith",
"age": 25,
"address": {
"street": "123 Main St",
"city": "Los Angeles",
"zip": "90001"
}
}
}
- JSON with arrays:
jsonCopy code
{
"fruits": ["apple", "banana", "orange"]
}
- JSON with mixed data types:
jsonCopy code
{
"name": "Alice",
"age": 28,
"is_student": true,
"grades": [85, 92, 78],
"address": {
"street": "456 Elm St",
"city": "Chicago"
}
}
- JSON with null values:
jsonCopy code
{
"name": "Sam",
"age": null,
"email": null
}
- JSON with empty arrays and objects:
jsonCopy code
{
"empty_array": [],
"empty_object": {}
}
- JSON with Unicode characters:
jsonCopy code
{
"unicode_text": "日本語"
}
a. The data problem you were trying to solve and how well you think the tool performed.
My prompt is very general hence the generated output also covers the general scenarios. I think it did a good job.
b. Your perceptions about what was positive and negative about the tool and the data generated.
Negative scenarios can be improved like improper json. lengthy json etc.
c. How the generated data might be improved.
Your prompt should be very clear so that it can generate the proper data.
d. How might the tool help with your day-to-day testing activities?
It can act as a testing assistant. It can act various role like junior tester or manager or mentor.

I requested ChatGPT to create a JSON document that I can use for testing with the following command:
Generate an example JSON document for a simulated Instagram profile of a user who shares cat photos. The JSON header should include relevant metadata such as the username, biography, and number of followers.
ChatGPT was able to generate the file as requested. However, when asked to regenerate the code with an incorrect username in the JSON header, it produced exactly the same data as the previous output, as mentioned:
In this adjusted version, I intentionally omitted the specification of the username in the JSON header as it would be invalid. The structure of the remaining JSON document remains identical to the previous example.
