a dependency between the component and the injector, but once the injector is configured, the component is not able to get more services.
People tend to choose dependency injection because it is easier to test. The key point is that you can use a real service or a test service created using stubs piles or mocks methods for testing purposes. But there is no difference in actually using dependency injection and service locators: both are well-supported
Sometimes, we encounter some requirements related to the current time of the system, such as:
Only the opening season is allowed to enter student information
It's only in the evenings or Saturday to allow backup blogs.
Users who have registered for 3 days are allowed to do something
A user is banned from speaking within 24 hours
It is clear that the code to implement these functions is more or less a DateTime.Now static attribute, but to use unit testing or integration testing

the benefits less than the effort.What is Dependency injectionIf we want to inject dependency, we must first understand what dependence is. To put it simply, dependency is the coupling between two modules in our code (in object-oriented languages, two classes), usually one of which uses another provided function.Why is Reliance Dangerous?Dependencies from the upper to the bottom are dangerous because we are coupling two modules to some extent, so that when one of the modules needs to be modifie

11, from the external testing
In some cases, you need to test the package from the outside of the package, such as the test code under the packages Foo_test, rather than the packages foo.
This can break the dependency cycle, such as:
–testing Package Using FMTThe test code for the –FMT package must also be imported into the testing package– The test code for the FMT package is then placed under the Fmt_test package so that both the testing package can be imp
the –FMT package must also be imported into the testing package– The test code for the FMT package is then placed under the Fmt_test package so that both the testing package can be imported or the FMT package can be imported at the same time.
12, mocks and fakes
You can avoid using mock and fake test mechanisms by using Interface,go in your code.
For example, if you are writing a file format parser, do not design functions like this:

them so they can be run lo Cally with mocks or stubs, or at the very least with a in-memory database, and let the build server run them in the slow The. People should not has to wait for computers, because if they has to, they would take shortcuts, which often causes proble MS for others instead.Invest time in making the system fast to work with. It increases flow, lessens the reasons for working in silos, and in the end makes it possible to develop

To understand rspec, we need to first understand what is behaviour driven development (BDD), and BDD is an acceptance test driven planning ), domain driven design and agile development model of test driven development (TDD. Rspec provides TDD support for BDD development.
