Before any new feature or tool makes it to Instaustad, it goes through a process that we think of as reality-checking. We don't just want to know if the code runs — we need to know what happens when things get messy.
It's easy to build a tool that works when a user pastes a perfectly formatted, public post link. But the real internet isn't perfect. People paste links to private accounts, they paste links that are missing the end string, they link to posts that were deleted five minutes ago, and they try to pull captions that are basically an entire short story made of emojis.
The Principle
If it breaks, it should break cleanly.
Manual Over Automated
We test things manually with real scenarios. Automated test suites are great for catching syntax errors, but they are terrible at pretending to be a real person who just copied a link from an old group chat and wants to see what the post said. We sit down and try to break the tool ourselves, feeding it every weird, malformed, or unexpected input we can think of.
One of the most important things we test for is private accounts. The rule is simple: if an account is private, we should not return data. Our tool should respect that privacy and return a clear message explaining why nothing was found.
Testing Error Messages
We spend a disproportionate amount of time testing error messages. Why? Because a bad error message is often worse than the error itself. If the tool fails and spits out a cryptic code, the user feels like they did something wrong, or they distrust the site.
When we test a deleted post, we check what the error says. Does it say "Data Null"? Or does it say "It looks like this post doesn't exist anymore"? We want our errors to be human-readable and helpful. If a test reveals that an edge case triggers a confusing error, we stop and rewrite the error handling.
Why We'd Rather Delay
Sometimes, this manual testing reveals something we completely missed. Maybe Instagram changed how they format video links slightly, and our parser chokes on the new format. When this happens, we don't just push the feature live and promise to fix it later.
We'd rather delay a release than ship something untested. It can be frustrating to hold back a tool that is 95% done, but shipping a broken tool damages trust faster than anything else. We are a small team, and our reputation is built on things actually working when you press the button.
