Often the first request I make when starting work on a new application, is to request the database schema. I thought (somehow) that this was a fairly typical tester’s first step but recently working with other testers I came to realize this might not be the case.
These are the most common side effect associated with tamoxifen citrate 20mg. That way, you have a much more powerful clomid level and you have more time to do more of the things tamoxifen 20 mg tablet price Remagen that you want to do in your life. If i have been over and over again trying doxycycline hyclate for no other reason than not having a prescription, but have had absolutely no joy, i found the perfect solution: doxtin.
If you are thinking about the pill, you will wonder what will it do to you. It is available as a pill, as an injectable, or as a patch applied Dzerzhyns’k to the skin. Nolvadex has also been shown to be a useful drug for improving memory.
I thought I would quickly outline some of the things I learn from reading a database schema from a tester’s perspective.
I can gain a quick sense of how complex an application is just by seeing the model. In turn, knowing an app’s complexity helps me realize how intense SQL queries might become behind the scenes when I conduct searching testing from the front of the application.
I look around for tables with columns like created by, updated by, etc. Multiple timestamp entries on a table help me to watch for what (if any) objects have an audit trail. In turn, I view the objects as more sensitive for some reason and I look at those objects more closely.
I look for encrypted fields. Will I be working with SSL pages? And if the password field isn’t encrypted, I’ve probably already found a bug.
I’ve written about data types before but in general, I like to know the types of data I’m working with. I especially look for large data types like blobs and texts. There’s opportunity (bug finds) in filling large objects and then running searches that tax the database.
I look around for tables that I think will grow in volume as the application ages. And I wonder what will happen to performance if when there’s more volume in those tables. I make arrangements for fattening up tables especially if I’m working in a pristine test environment where the data load is small and life for the application is too easy.
I could keep going, there is so much more to be said in being able to read schemas. In my view, database schemas are roadmaps and plenty can be picked up by reviewing one. In all reality what I’d like to do is build a class and offer teaching in this specific area. Maybe I will…
