I always had ’test data generation’ in mind when I created the table editor. conversion becomes “import from csv to internal data set” and “export from internal data set to Markdown”. So I only have to ’export to’ and ‘import from’ a single data set for each format, and I get ‘conversion’ for free, e.g.

I wanted to learn how to implement drag and drop file uploading in JavaScriptīut these were core to the feature set in the application and easy to justify.Īdding extra imports and exports was useful because it forced me to abstract the data structures to have a single internal representation of a data set to make it easier to work with.

I wanted to learn how to ’export’ from a page to file.

I wanted to learn how to load files into a browser.

Some of the features of the tool were driven by a desire to experiment: One of the dangers with tool creation is that I end up adding features ‘because I can’, this is fine when I’m using the tool to learn a language but as soon as I create something that is useful I have to be careful about what I add.įor this tool, I tried to keep the functionality set to the core of data editing. There are more repos like the above in my Github Profileīut primarily, I try to create applications and tools as it helps put concepts into context. I’ve started creating ‘faq’ style repos with small examples to make sure I learn the Unit Test Frameworks for the language at the same time: The way I learn most languages is by creating applications. I then wrote a simple routine to parse the grid data and create Markdown tables as well.Īnd I thought I’d probably just stop there. I didn’t really want to do much more than:īut that was simple enough and I added a custom header in the grid columns to have links to add that functionality.įairly quickly I had a CSV editor. I wanted a flexible data grid, which ‘just worked’ without my having to do much coding.

If you sign in using your Google account, you can download random data programmatically by saving your schemas and using curl to download data in a shell script via a RESTful url.What happens if you combine a table editor with test table generation? You get a tabular random table generation tool.Īmong the many tools, games and apps that I’ve written sits a “ Markdown and CSV Table Editor”. Mockaroo allows you to quickly and easily to download large amounts of randomly generated test data based on your own specs which you can then load directly into your test environment using SQL or CSV formats. But not everyone is a programmer or has time to learn a new framework. There are plenty of great data mocking libraries available for almost every language and platform. Testing with realistic data will make your app more robust because you'll catch errors that are likely to occur in production before release day. Real data is varied and will contain characters that may not play nice with your code, such as apostrophes, or unicode characters from other languages. When you demonstrate new features to others, they'll understand them faster. When your test database is filled with realistic looking data, you'll be more engaged as a tester. Worse, the data you enter will be biased towards your own usage patterns and won't match real-world usage, leaving important bugs undiscovered. If you're hand-entering data into a test environment one record at a time using the UI, you're never going to build up the volume and variety of data that your app will accumulate in a few days in production. In production, you'll have an army of users banging away at your app and filling your database with data, which puts stress on your code. If you're developing an application, you'll want to make sure you're testing it under conditions that closely simulate a production environment. Paralellize UI and API development and start delivering better applications faster today! Why is test data important? With Mockaroo, you can design your own mock APIs, You control the URLs, responses, and error conditions. By making real requests, you'll uncover problems with application flow, timing, and API design early, improving the quality of both the user experience and API. It's hard to put together a meaningful UI prototype without making real requests to an API. Mock your back-end API and start coding your UI today.
