Functional tests are a useful thing. At first they do not take much time, but the project is growing, and more and more tests are needed. We did not intend to endure the slowdown in the speed of delivery and, gathering strength, accelerated the functional tests three-fold. In the article you will find universal advice, however, you will notice a special effect on large projects.

My team is developing a public API that provides data to users of 2GIS. When you visit 2gis.ru and search for "Supermarkets", you get a list of organizations - this is the data from our ...[/h]

 
It's a trick that I learned about recently from the Android Android Developer in my company, and now I feel unhappy, regretting the time I spent waiting for the Gradle build to check my changes when writing Android applications.
 
Here is a typical scenario that every Android developer could meet at least once during its development life cycle. You have a list of the items you want to show in

or
RecyclerView

Below is our beloved method onBindViewHolder , which connects your model to your view-components RecyclerView .

Most often from game developers you can hear a very simple phrase: it's surprising that games generally come out. Games are complicated, untamed monsters, connected by something like digital insulating tape. It's not surprising that they fall apart.

I was informed that on some new computers some regression tests became slower. It's common, it happens. Incorrect configuration is somewhere in Windows or not the most optimal values ​​in the BIOS. But this time we could not find the "adjusted" setting. Since the change is significant: 9 to 19 seconds (blue on the graph is old iron, and orange is new), then we had to dig deeper.

Simple code for debugging is code that does not fool you. It is more difficult to debug code with hidden behavior, with poor error handling, with uncertainties, insufficiently or excessively structured, or in the process of changing. In fairly large projects, you eventually encounter a code that you can not understand.
 
 
If the project is relatively old, then you can find code that you forgot about, and if it were not for the commits, you would have sworn that you did not write these lines. As the project grows, it becomes more difficult to remember what the different pieces of code are doing. And ...

 
As you know, compatibility with GNU tools and GDB support make almost any popular development environment suitable for debugging a wide range of embedded platforms, mostly free of charge and legally. In theory.

Introduction

 
There are several articles on the antipatterns of software development. But most of them talk about the details at the code level and focus on a specific technology or programming language.
 
 
In this article, I want to take a step back and list the high-level antipattern testing common to all. I hope you will learn some of them regardless of the programming language.
 
 

Terminology

 
Unfortunately, the testing has not yet developed a common terminology. If you ask a hundred developers what the difference between an integration, cross-sectional and component test is, you'll ...[/h][/h]

Why so it is important forbid self-debugging with your hands?
 
 
When you debug a program, you yourself, without realizing it, think that for one debugging session, fix all the problems that have arisen in the framework of this task. But our shortsightedness does not want to believe that in fact there is not one problem, but several. And for one debug session it will not be possible to solve all these problems.
 
 
Therefore, you will need to run this code several times in debug mode, spending hours debugging over the same piece of code. And it's only you alone spent so much time on this ...
