I can test the whole thing by hand, click through every path, catch the bugs. But the moment someone says to automate it, I freeze. Setting up the framework, writing tests that run themselves, it feels like a wall I can't climb, so I keep doing it all by hand and falling further behind.
More people experience this than they realize.
You can test by hand but automating it overwhelms you.
If this sounds familiar, the Library can help you find the bigger picture.
