As you can see from this example, the Ubuntu operating system provides many ways to control the start and stop of services and programs. In startup scripts, you can describe dependencies on other services using "Required-Start/Required-Stop" sections, and the script itself can be of any complexity, allowing you to fine-tune any startup configuration.

## Conclusion

While the solution worked, it was not without its drawbacks. Due to the nature of desktop automation, it was not possible to run tests in parallel mode on the same machine/session, or to run tests in headless mode. Each CI agent required additional configuration to run these tests. In addition, these tests were quite slow because it takes time to run a process as heavy as an MS Office application. Therefore, we had to keep an eye on the scenarios we were automating to maintain a small test suite. The focus was on other testing solutions, while scenarios that needed to run in the Microsoft Office environment had to be written using this framework.

I had to accept the fact that I needed a custom solution. During my research, I found an interesting example of an application that aims to test the startup performance of desktop applications by launching the application and detecting the point at which the application becomes visible and waits for idle input.
This was pretty close to what I was looking for, so I decided this was a good starting point for my idea. However, I had to work around its limitations: it won't work for complex applications and it can't be extended to add additional features.

The solution is designed based on analysis of target applications and may not work for other applications. It's completely up to the application implementation, and plug-in initialization can be fully parallel or delayed until the main process is fully loaded, so you won't affect startup performance in any way.

The selectors I mentioned earlier, which we use to find elements on a page, were designed primarily for development, not testing. However, as testers, we should focus more on how real users perceive and interact with the UI than on the technical details of the implementation. Our locators and tests should be able to catch any changes in the UI that break the expected user flow and experience, not just technical bugs. The goal is to ensure that the UI works as intended for the end user, not to validate the code.

There are frameworks that support a different approach to writing UI tests. They are built from the ground up for testing and focus more on user interaction, such as the [Testing Library](https://testing-library.com/docs/queries/about/#priority) and [Playwright](https://playwright.dev/docs/locators). They suggest using specific functions like `getByRole()`, `getByText()`, etc. that mimic how real users perceive the elements, reflecting the experience of visual/mouse users as well as those using assistive technology like screen readers. I think this is a great step towards a way that is closer to how software is used by end users, while making selectors resilient to change.

At first I thought about separate desktop and mobile applications and how to synchronize data between them. However, I decided to simplify things and go with an SPA application that could run in the browser on any device.

Devcontainer images are a bit different from typical images. Devcontainer images come with pre-built tools and runtime stack specific to development container image, also they are not designed to be used for hosting applications in production as permissions and OS configuration could be adjusted to make it easier to use. But what makes a huge difference is the Visual Studio Code Server that runs inside the container, which allows you to run formatters and linters, use a predefined list of Visual Studio Code extensions, and even scan the container output and integrate all of this with the IDE running locally. So you are basically using the IDE as a terminal to connect to the remote development environment.

Would I recommend using it? Well, it depends. There are no good or bad tools, and this one is no exception. I believe it needs more time to discover and reduce common issues related to it's usage, IDE support and can become a great seamless one-click way to spin up development environment. While it looks feature-rich even today, it is necessary to compare all the pros and cons for a particular project to make a proper decision. Nevertheless, I would recommend everyone to give it a try and integrate it into a smaller project to see how easy development environment management can be.
