Expect vs. Where Expected

Attribute	Expect	Where Expected
Definition	Anticipate or look forward to something happening	Anticipated to happen in a specific location or situation
Usage	Used to express anticipation or belief in something happening	Used to specify the location or situation where something is anticipated to happen
Function	Used to set up expectations or predictions	Used to indicate the specific context or condition for expectations
Examples	"I expect the package to arrive tomorrow."	"I expect to see you at the meeting."

Introduction

When it comes to software testing, two commonly used methods are Expect and Where Expected. Both of these techniques are used to verify the behavior of a system or application, but they have some key differences that make them suitable for different scenarios. In this article, we will compare the attributes of Expect and Where Expected to help you understand when to use each method.

Definition

Expect is a testing technique that involves defining the expected outcome of a test case before running it. This means that the tester specifies what the result should be, and the test will pass only if the actual outcome matches the expected one. On the other hand, Where Expected is a technique that focuses on identifying the specific areas in the code where certain behaviors are expected to occur. This method is more about pinpointing the exact locations where certain conditions should be met.

Usage

Expect is commonly used in test-driven development (TDD) where tests are written before the actual code is implemented. By defining the expected outcome upfront, developers can ensure that their code meets the desired specifications. Where Expected, on the other hand, is often used in regression testing to verify that specific conditions are met in the codebase. This method is useful for ensuring that changes to the code do not inadvertently affect certain behaviors.

Flexibility

One of the key differences between Expect and Where Expected is their flexibility. Expect allows testers to define the expected outcome in a more general sense, which can be useful for high-level testing. Where Expected, on the other hand, requires testers to identify specific locations in the code where certain conditions should be met, making it more rigid and less adaptable to changes in the codebase.

Granularity

Another important aspect to consider when comparing Expect and Where Expected is the granularity of the tests. Expect tends to focus on the overall behavior of the system, looking at the end result of a test case. Where Expected, on the other hand, zooms in on specific areas of the codebase to verify that certain conditions are met. This makes Where Expected more suitable for pinpointing issues at a more detailed level.

Automation

Both Expect and Where Expected can be automated to some extent, but they require different approaches. Expect can be easily automated using testing frameworks that allow for the definition of expected outcomes. Where Expected, on the other hand, may require more manual intervention to identify the specific locations in the code where conditions should be met. This can make automation more challenging for Where Expected tests.

Conclusion

In conclusion, Expect and Where Expected are two valuable testing techniques that serve different purposes in software testing. Expect is more flexible and suitable for high-level testing, while Where Expected is more rigid and focused on pinpointing specific areas in the codebase. Understanding the attributes of each method can help testers choose the right approach for their testing needs.
