What does it mean when code is unreachable?
In computer programming, unreachable code is part of the source code of a program which can never be executed because there exists no control flow path to the code from the rest of the program.
Which of the following testing techniques identifies the unreachable code and checks for code coverage?
It identifies the unreachable code, memory leaks, and other coding related errors. White box testing helps maintain clean and optimum code conforming to the coding standards. These test cases are easy to automate as each targets a section of code. It helps improve the quality of the product enormously.
How can solve unreachable code in C++?
Just add a premature return while working on the code in the function or the code calling the function.

What is unreachable statement error in Java?
The Unreachable statements refers to statements that won’t get executed during the execution of the program are called Unreachable Statements. These statements might be unreachable because of the following reasons: Have a return statement before them. Have an infinite loop before them.
How do you find the dead code?
The quickest way to find dead code is to use a good IDE. Delete unused code and unneeded files. In the case of an unnecessary class, Inline Class or Collapse Hierarchy can be applied if a subclass or superclass is used. To remove unneeded parameters, use Remove Parameter.
What is unreachable catch block error explain with example?
When we are keeping multiple catch blocks, the order of catch blocks must be from most specific to most general ones. i.e subclasses of Exception must come first and superclasses later. If we keep superclasses first and subclasses later, the compiler will throw an unreachable catch block error.
How do you fix an unreachable error in Java?
1(a) is compiled, line 12 raises an unreachable statement error because the break statement exits the for loop and the successive statement cannot be executed. To address this issue, the control flow needs to be restructured and the unreachable statement removed, or moved outside the enclosing block, as shown in Fig.
How do I fix unreachable?
Most customers have reported that restarting the router has resolved the ERR ADDRESS UNREACHABLE problem. You only need to turn off your router’s power source and wait 2–5 minutes. Then switch it on and, after a few seconds, connect your computer to the internet.
What are the types of code coverage testing?
Two common forms of test coverage are statement (or line) coverage and branch (or edge) coverage. Line coverage reports on the execution footprint of testing in terms of which lines of code were executed to complete the test.
What are white box testing techniques?
White-box testing (also known as clear box testing, glass box testing, transparent box testing, and structural testing) is a method of software testing that tests internal structures or workings of an application, as opposed to its functionality (i.e. black-box testing).
In which of the following testing techniques defects can be found more easily?
Defects can be found more easily in: – Manual testing.
What does unreachable code mean in solidity?
Unreachable code, a part of the source code that will never be executed due to inappropriate exit points/control flow.
Which of following is called as dead code?
Dead code is any code that’s never executed, or if executed, the execution has no effect on the application’s behaviour.
Is one or more than one code statements which are either never executed or unreachable?
Dead code is one or more than one code statements, which are: Either never executed or unreachable, Or if executed, their output is never used.
What does unreachable code mean in solidity?
Unreachable code, a part of the source code that will never be executed due to inappropriate exit points/control flow.
What is test harness in manual testing?
In software development, a test harness is a collection of software and test data used by developers to unit test software models during development. A test harness will specifically refer to test drivers and stubs, which are programs that interact with the software being tested.
What is checklist based testing?
An experience-based test design technique whereby the experienced tester uses a high-level list of items to be noted, checked, or remembered, or a set of rules or criteria against which a product has to be verified.
What is coverage measurement in testing?
Test coverage measures how much your tests are covering things like test requirements, code, different user scenarios, and platforms such as mobile devices or browsers. It is a useful metric for measuring the effectiveness of your testing efforts. Test coverage is important for finding defects before they reach users.
