1. Introduction to type assertion That is, for values without type declaration, sometimes when ts type inference, the inference result is incorrect, so ts provides a type assertion method to tell the compiler what type the value here is. , and once ts discovers that there is a type assertion, it will no longer perform […]

Spring Cloud Alibaba GateWay’s routing assertion factory
Spring Cloud Gateway uses route matching as the most basic function. This function is accomplished through the routing assertion factory. Spring Cloud Gateway contains many built-in routing assertion factories. All these assertions can match different attributes of HTTP requests, and multiple routing assertion factories can be combined based on logic and status. 1. After routing […]
Test JSON data format using Pytest and Schema assertions
Foreword During the test process, the author received such a test task. After the interface was refactored, test students were required to verify the structure and type of the data to prevent an increase in the probability of hidden problems due to a field being deleted or the type being changed. So how to verify […]
Web Automation Testing: Test Case Assertions!
When running a test case, we need to determine whether the test case is executed successfully. At this time, we need to have an expected result for verification. In the unittest here, if an error is reported during the execution of a case, or we judge that the result does not meet expectations, it will […]

09 | Usability Improvements II: Literals, Static Assertions, and Member Function Specifiers
In this lesson we continue the topic of usability and look at other usability improvements brought by modern C++. Custom literals Literals refer to fixed constants written in source code. They can only be primitive types in C++98, such as: “hello”, string literal, type is const char[6] 1. Integer literal, type is int 0.0, floating […]
IDEA Rebuild project error: Information:java: java.lang.AssertionError: Value of x -1
Problem: java.lang.AssertionError: Value of x -1 Imitating the lombok tool, my enumgen tool is basically finished. After the release, it was overturned when it was ready to be put into production! After the company’s project emax-rpcapi-list relies on enumgen, when IDEA Rebuild Project or when maven package/install, an error occurs → Information: java: java.lang.AssertionError: Value […]
17｜Standard Library: Assertions, Error Handling and Alignment
This lecture is the final lecture on the C standard library. Through the previous lectures, I believe that you have a comprehensive understanding of the relevant capabilities provided by the C standard library. On this basis, you can use these mature interfaces to build applications more conveniently. After this lecture, in other chapters of “C […]
Cypress web automation 6- Assertions assertion use (should, expect)
Foreword Each test case needs to add assertions. Commonly used assertions in Cypress include should and expect. Implicit assertion .should() You can use .should() to add assertions to the current use case should(‘have.class’, ‘success’) asserts that the value of the class attribute of the element is ‘success’ should(‘have.text’, ‘Column content’) asserts the element text value […]
