Should asserts be used in production code?
Table of Contents
In the Java guideline, it is said that “assertions are only intended for debugging and bug hunting, but should be removed in production code”. I personally like to write assertions to get notified of invalid program states during testing and let them be deactivated in production.
What is assert in code?
An assertion is a statement in the Java programming language that enables you to test your assumptions about your program. For example, if you write a method that calculates the speed of a particle, you might assert that the calculated speed is less than the speed of light.
Can I use assert in production?
JUnit assertions are intended to be used in test code, but not in production code.
Are asserts good practice?
Yes it is good practice. In the Spring case, it is particularly important because the checks are validating property settings, etc that are typically coming from XML wiring files.
When should I use assert?
You can use an assert to check if your logical assumption is correct. You can also use assert statements to check if the control flow is correct or not. For example, if you have a function that returns a value, you may want to put an assert statement. However, you may get a ‘non-reachable’ code error.
Is assert good?
Do use asserts sparingly when the distance between cause and effect is not immediate and hence reducing the side effects. Do use asserts to prevent your system from going into an inconsistent or non-performant state due to programmer errors. Assertions are great for runtime (i.e external cause errors).
What does assert mean in python?
The assert keyword lets you test if a condition in your code returns True, if not, the program will raise an AssertionError. You can write a message to be written if the code returns False, check the example below.
Should I use assert in Python?
Assert statements are used to debug code and handle errors. You should not use an assert statement in a production environment. Debugging is a crucial part of programming in any language. When debugging programs in Python, there may be times when you want to test for a certain condition.
Should assertions be in production code?
Normally, you don’t want users to see assertion messages in production code; assertions are primarily for use during development and maintenance. Assertions are normally compiled into the code at development time and compiled out of the code for production. However, later in the same section, this advice is given:
What is the section on assertions?
The section on Assertions is 8.2. Normally, you don’t want users to see assertion messages in production code; assertions are primarily for use during development and maintenance. Assertions are normally compiled into the code at development time and compiled out of the code for production.
When should assertions be compiled?
Assertions are normally compiled into the code at development time and compiled out of the code for production. However, later in the same section, this advice is given: For highly robust code, assert and then handle the error anyway.
Should I use require () or assert () in release builds?
Since a failed assertion indicates a bug, it should be treated seriously even in a Release build. When my code’s performance matters, I will often use REQUIRE () for higher-level code and assert () for lower-level code that must run fast.
