The basics of testing, the basics of testing

A 1:50000 topographic map has 1 point p (2702000 m, 18281000 m), and after proper calculation: (1) How far is this point p from the equator?

2) How many projection bands is the topographic map located in? (3) Does the topographic map use a 3° zone projection or a 6° zone projection? (4) What is the **meridian longitude corresponding to this projection belt?

5) What is the natural y coordinate of p?

1. Why do you need a soft and stuffy training test?

2. Why choose software testing.

3. Why not let the developers do the tests themselves.

1. Definition of software testing.

By hand or with tools"The object to be measured"Perform a test operation to verify that there is a discrepancy between the actual and expected results.

Second, the role of software testing.

3. Test Principles:

The so-called testing principles refer to the rules that we must follow when performing testing work.

For the current testing industry, the subject we test most often is software (main function), but we need to understand that a software is not only a function that needs to be tested. We can divide the software into three parts: function collection + instruction manual + configuration data.

The development of the software will be based on the correspondingDevelop a model, the test level refers to the development steps that we have artificially defined in this model, and the most common level of test is classified as follows:

1. Classification according to test objects.

Second, according to whether the test object is classified.

3. Classification according to test methods.

To describe whether the current software is good or not, the set of standards we use in the current software industry is based on the ISO organization. What we need to memorize are the six characteristics of software quality:

The so-called software architecture can be understood as an idea that is used to guide our software development. By far, the two most common framework patterns are b s and c s

b---browser--- browser.

c---client---client.

s---server --- server.

2. Comparison of the two architectures.

First, the browser is Shimo.

The browser is essentially a piece of software, installed on the operating system, and generally provides users with the service to browse the page. For now, we're going to artificially summarize all browsers into a so-called Big Five. [For browsers, the core technology is the kernel].

Second, the five major browser manufacturers.

1. Function: actual function.

2. UI: Compare with the design drawing, text size, color source simplification, margins, typography, and clarity stretching.

3. Compatibility:

2）web:

Trident: IE, 360 compatibility mode, Sogou compatibility mode.

Gecko: Firefox.

blink: chrome (Google speed mode, Sogou speed mode.

webkit：safari

4. Interface: 1) Interface function: postman

2) Interface performance: jmeter, loadrunner 3) Interface automation: requests

5. Ease of use: whether it is easy to use.

6. Performance: pressure, stability, load test, benchmark test.

7. Security: password encryption, access permission, SQL attention, XSS attack, cross-site attack.

8. Automated testing

The first thing you need to understand is the introduction to the composition of computer systems, including the composition of computer systems, the abstract hierarchy of computer systems, the definition of software, and the basic classification of software. To familiarize yourself with the definition and main functions of the operating system, commonly used operating systems. Also be familiar with decimal conversions, including number, decimal, binary, octal, hexadecimal, and the conversions between them.

Familiar with the definition of logical algebra, basic logical relations and operations, and logical variables. Master the fundamentals of computer networks, including understanding networks, network protocols, hierarchical ideas, common network layering models, and corresponding functions and protocols of each layer.

Secondly, it is necessary to master the life cycle of software and be familiar with the software development process model, including waterfall model, rapid prototyping model, and spiral model. Master the software testing process model, including V model and W model. Lay a good foundation for the systematic learning of software testing in the future.

It is also necessary to grasp the definition of software testing, be familiar with the purpose of software testing, the significance of software testing, and master the software testing workflow and the actual software workflow. Through the study of the introduction to software testing, students will be familiar with the software testing workflow and cultivate good habits in future testing work.

In addition, it is also necessary to master the definition of software defects, be familiar with the causes of defects and the second definition of software defects, and master the preparation of defect reports. Through the learning of software defects, learn how to submit defect reports in daily work, and clarify the severity and priority of bugs.

Q: There seem to be a lot of testing companies now, but each has different requirements, if you want to make a breakthrough in 5 years, how can you become a good tester, and how many things do you need to master? A must-have?

I'm interested in embedded testing and don't know what to learn? I'm still young and want to learn more, and I hope my seniors will give me more advice! Appreciate!!

A: Testing is a very practice-oriented discipline, if you are interested in embedded system testing, it is recommended to enter a company that does embedded products for testing work, otherwise it is difficult to get started.

There are a lot of things that need to be mastered to become a good tester, and here are the directions that I think need to work on, and I am working on it myself :):

1. Computer professional knowledge, at least with theoretical knowledge of various disciplines in computer science, this is not much to say;

2. The professional domain knowledge of the test object, for example, if you are testing routers, then you should have basic knowledge of communication majors, as well as knowledge related to routers, such as OSPF, RIP, etc., if you are testing banking financial business, you should be familiar with the business processes of the bank, if it is an embedded system product, then you have to learn operating systems such as VXWaws, 8260 and other CPUs, hehe, is it a bit bad :)

3. Testing professional knowledge, including testing technology, testing methods, testing principles, quality principles, testing management, testing tools, defect analysis, testing measurements, etc.

4. The development of communication skills testing is endless, as long as you work hard, I think 5 years should be enough to break through the above content.
