How Do You Find The Independent Path?

1. Independent Paths = Edges – Nodes + 2.
2. Independent Paths = Regions + 1.
3. Independent Paths = Decisions + 1.

What are independent paths?

Independent path is

a path through a Decision to Decision path graph which cannot be reproduced from other paths by other methods

. Advantages of Path Testing: Path testing method reduces the redundant tests. Path testing focuses on the logic of the programs. Path testing is used in test case design.

What is linearly independent path?

Linearly independent path A linearly independent path is

any path through the program that introduces at least one new edge that is not included in any other linearly independent paths

. If a path has one new node compared to all other linearly independent paths, then the path is also linearly independent.

What is independent path in graph?

An independent path is

one that represents a path in the program that traces a new set of procedural statements or conditions

. If we take it in the context of a flow graph, the independent path traces the edges in the flow graph that are not traversed before the path is defined.

What are the two types of path testing?

Path Testing Techniques:

Decision to Decision path (D-D)

– The CFG can be broken into various Decision to Decision paths and then collapsed into individual nodes. Independent (basis) paths – Independent path is a path through a DD-path graph which cannot be reproduced from other paths by other methods.

When can we say 100% path coverage is achieved?

To achieve 100% path coverage,

every path from the entry node to the exit node of the CFG of the program must be traversed during at least one execution of the program

.

What is an achievable path?

If you can find a solution, then the path is

achievable. If you cant find a solution to any of the sets of inequalities, the path is un achievable. The act of finding a set of solutions to the path predicate expression is called PATH SENSITIZATION.

Is it true basic path testing covers dependent paths?

Basis Path Testing is a white-box testing technique based on the control

structure

of a program or a module. Using this structure, a control flow graph is prepared and the various possible paths present in the graph are executed as a part of testing. Therefore, by definition, … Design Test cases from Independent Paths.

Is an independent path of execution within a program?

An independent program path is one that traverses at least one new edge in the flow graph. In program terms, this means exercising

one or more new conditions

. Both the true and false branches of all conditions must be executed.

What do you mean by coincidental correctness?

Coincidental correctness occurs when a wrong function is executed, but due to some coincidence, the output is the same as if it were computed by the correct function. Coincidental correctness occurs

when no failure is detected even though a fault has been executed”

.

What are path products?

The

name of a path that consists of two successive path segments is conveniently expressed by the concatenation or Path Product of the segment names

. For example, if X and Y are defined as X=abcde,Y=fghij,then the path corresponding to X followed by Y is denoted by. XY=abcdefghij.

What is blackbox techniques?

Black box testing is

a technique of software testing which examines the functionality of software without peering into its internal structure or coding

. … If the function produces correct output, then it is passed in testing, otherwise failed.

How do you do path testing?

1. Draw a control graph (to determine different program paths)
2. Calculate Cyclomatic complexity (metrics to determine the number of independent paths)
3. Find a basis set of paths.
4. Generate test cases to exercise each path.

What is DD path concept is known as?

A decision-to-decision path

, or DD-path, is a path of execution (usually through a flow graph representing a program, such as a flow chart) between two decisions.

What are the nice domains?

Some important properties of nice domains are:

Linear, Complete, Systematic, Orthogonal, Consistently closed, Convex and Simply connected

. To the extent that domains have these properties domain testing is easy as testing gets. The bug frequency is lesser for nice domain than for ugly domains.

What is known as path sensitizing?

What is path sensitization? Approach: • by path sensitization we identify

a signal path from a fault site to an observable output

, where. the logical state of any gate output along that path is dependent on/sensitized to logic value at fault site.
