This article mainly explains the "Java as the main line of test development technology stack analysis summary", the article explains the content is simple and clear, easy to learn and understand, now please follow the editor's ideas slowly in-depth, together to study and learn "Java as the main line of test development technology stack analysis and summary" bar!

Basic knowledge of Java

Data type

8 basic data types: byte, short, int, long, float, double, char, boolean

Three reference data types: class, interface, array

Conditional statement application

Loop statement application

The common method of String is to find, concatenate, replace and delete strings.

Array and dynamic array (arraylist)

Hashmap

Regular expression

Java functions, including function definitions, parameters, and return values

Exception Mechanism of Java

Java naming convention

Object-oriented inheritance, encapsulation and polymorphism

The concept of JavaIO and the reading and writing of files

Maven fundamentals, focus on: installing maven environment, creating maven project, maven engineering structure, pom.xml, using maven in ide

Git\ SVN basic usage

Testing framework Junit4 and TestNG

UI automated testing

Core: automated testing using java's jar package + Java testing framework

If you do automated testing of web applications, use the selenium jar package

If you do automated testing of IOS or Android applications, use the appium jar package

Interface automation test

Core: automated testing using java's jar package + Java testing framework

If you are testing the http or https interface, use the httpclient jar package

If you do other types of interface testing (including TCP, UDP, dubbo, etc.), you need to communicate with R & D, what is the specific protocol? How to invoke the service interface? Because the essence of interface testing is (take java as an example), call a method in the class through an instance of the new class!

Test gadget development

Core: solve the repetitive work of manual testing through code. Here are a few examples.

Test data creation: you can create test data by writing sql statements + UI automation + interface automation

Test environment construction: mainly python,shell+ansible

Excel document related processing: using poi-ooxml jar packages

Jenkins task processing: using jenkins-client jar

Test platform development

From a personal point of view, test platform development is essentially development, but only the development of test-related products. Then you need to have a more in-depth understanding of Java development, including:

Container

Multithreading

Reflection

Generics

Design patterns, focusing on: factory design patterns, singleton patterns, agent patterns, template methods, wrapper patterns, observer patterns and adapter patterns

Since most of the test platforms are developed based on the Bamp S architecture, we need to master the front and back end related technologies.

The knowledge that needs to be mastered at the back end includes:

Spring, back-end infrastructure

Spring MVC, a MVC framework based on Spring

The concept of micro-service

Spring Boot, a set of rapid development integration package based on Spring conditional registration, is the most mainstream technology at present.

Spring Data JPA, manipulate the database

MyBatis, manipulate the database

The comparison between Spring Data JPA and MyBaits is as follows

1. Table is associated with more items, giving priority to using mybatis

two。 Mybatis is recommended for projects that continuously maintain faster development iterations because it is more flexible.

3. For traditional projects or projects with a clear and stable relationship model, JPA is recommended.

Spring Boot message driver (including: KafkaTemplate, RabbitTemplate, etc.)

The knowledge to be mastered at the front end includes:

HTML

DOM

Javascipt

Css

Vue

React

Thank you for your reading, the above is the content of "Java as the main line to analyze and summarize the technical stack of test development". After the study of this article, I believe you have a deeper understanding of the problem of technical stack analysis and summary of test development based on Java, and the specific use needs to be verified in practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
