How did I get started?
I am studying in an ordinary university. I started my internship to look for a job when I was in college, and accidentally entered a start-up company engaged in the big data industry.
At the beginning, I did not have a clear career development direction, mainly doing some basic work of environment building. However, due to high execution efficiency and strong sense of responsibility, I was appreciated by the boss of the company during my internship and was assigned to be in charge of project testing. After graduation, I was transferred to the test engineer of the product R&D Department.
Most of my work is based on functional testing, but also on business trips and part-time work for various products, operation and maintenance, pre-sales, in short, where the company needs, I will rush. Although the starting point is not high, I have learned a lot from my testing experience, including functional testing, UI automation testing, interface automation testing, performance testing, security testing and compatibility testing.
I will also quickly learn various skills according to work needs, such as computer programming, network, storage, scheduling and other knowledge, which also lays a foundation for my later study of continuous integration and data center.
What have I learned in starting a small business?
Testing is all about results, and the norm for small startups is tight schedules, multiple tasks, and rapid iteration.
So how to deal with this challenge, efficiently complete the test work, smooth guarantee project quality?
After a variety of work pressure, practical exploration and bumpy experience, I figured out the core points: sorting out the r&d process of the company’s existing products, and making clear how to carry out testing work in each stage of r&d.
To put it simply, it is to understand the key steps of the whole process of developing and executing software tests:
1. Obtain requirements, functional designs, detailed design specifications and other required documents
2. Obtain budget and time requirements
3. Identify project stakeholders and their responsibilities, reporting requirements, required standards and processes (e.g. version process, change process, etc.)
4. Identify high-risk applications, set priorities, and determine the scope and limits of testing
5. Determine test methods — unit test, integration test, system test, acceptance test, etc
6. Determine environmental requirements (software/hardware/communications, etc.)
7. Determine test tools and environment (record/playback tools, coverage analyzer, test trace, problem trace, etc.)
8. Determine test input requirements
9. Identify tasks, task responsibilities and corresponding workload
10. Set time estimates, timelines, milestones, etc
12. Determine input equivalence classes, boundary value analysis, error classes
12. Prepare test plan documents and required reviews
13. Write test cases
14. Conduct necessary reviews of test cases
15. Prepare test environment and test tools, obtain required user manuals/reference documents/configuration guidance/installation guidance, establish tracking process, log and archive process, and obtain test data
16. Obtain and install the software version
17. Perform tests
18. Evaluate and report test results
19. Tracking problems and modifications
20. Retest if necessary
21. Maintain and modify test plans, test cases, test environments and test tools throughout the life cycle
After combing the development and software testing process, further clarify the testing work of each testing stage, stage objectives, main tasks, passing criteria, and finally test work, it will get twice the result with half the effort.
Why test development?
More than a year of work experience, let me deeply experience that clear process sorting is not enough. Within the company, the feedback cycle between development, team and test, operation and maintenance personnel is too long, resulting in many defects in software development process and quality:
- Testers wait for a “good” build;
- Bug reports are not received until several weeks after new features have been developed;
- Operations personnel are waiting for documentation or bug fixes;
From a testing perspective, I can think of many ways to improve the software delivery process, but it is difficult to implement. Because I do not write code, do not deeply understand the logic of r & D business implementation, I can not understand how this Bug appeared, can not see through the appearance of the essence. Sometimes the phrase “you don’t understand” makes me feel that communication is really difficult. The heart was held in one breath, I really wish I could be a person “sky”.
Only by becoming a test development engineer, who can both test and understand the code, can he maximize help in R&D and testing to improve the testing efficiency, and thus help the company to improve the overall R&D efficiency. This has become my unwavering goal of professional growth.
Quit your job to learn test development skills
Buffett and Munger said the best investment in the world is investing in yourself.
In order to learn test development technology, HE shared a set of courses from his friends (he spent about thousands of yuan to buy it at that time). He felt that the outline was comprehensive and the knowledge system was complete. At the same time, he also participated in many dry goods open courses of some website.
In 2020, due to the impact of the epidemic, a lot of testing work had to be handled remotely and online. However, team collaboration was not efficient and project iteration was still too fast. I always feel that after receiving the test work, I can only complete it as soon as possible, and it is difficult to implement it according to the original plan and reach the good standard. This kind of tired running and anticlimactic feeling, let me mute eat coptis, bitter can not say.
I hated this working mode so much that I could not bear it any longer. After a while, I decided to quit my job and officially stayed home to learn the Course “Advanced Python Automated Test Development”. On the one hand to adjust their current physical and mental state, on the other hand is also to break the cauldron, enrich themselves, to better their own – test development direction forward!
This course system of Python Automation Test Development is very comprehensive. Dachang’s cutting-edge technology and development direction are introduced in detail. It is full of dry goods and practical essence. After learning, digesting and absorbing the course knowledge, I directly applied it to the subsequent job interview, and successfully won the Offer from many companies. Finally, I chose a test development position with an annual salary of 20W+ in a factory, and the salary increase is 120%, which is really delightful ~
