Integration Testing - Reading Assignment

[lampacenter]

1.Why do we write integration tests?

That we test the code that makes apps.

2.What problems do integration tests solve?

Finds errors during use of apps and also tests all the subsystems and interfaces.

3.What are the differences between top-down and bottom-down approaches?

Top down starts with higher levels in code and proceeds to lower levels of code, Bottom up begins with unit testing and later the main functions.

[George21]

1. To create a development process which program units are combined and tested as groups in multiple ways.

2. Integration testing can expose problems with the interfaces among program components before trouble occurs in real-world program execution.

3. Bottom-up integration testing begins with unit testing, followed by tests of progressively higher-level combinations of units called modules or builds.
   In top-down integration testing, the highest-level modules are tested first and progressively lower-level modules are tested after that.

**Integration testing **

1. Why do we write integration tests? Integration testing, also known as integration and testing (I&T), is a software development process which program units are combined and tested as groups in multiple ways.
2. What problems do integration tests solve? Integration testing can expose problems with the interfaces among program components before trouble occurs in real-world program execution.
3. What are the differences between top-down and bottom-up approaches? Bottom-up integration testing begins with unit testing followed by tests of of progressively higher-level combinations of units called modules or builds. In top-down integration testing, the highest-level modules are tested first and progressively lower-level modules are tested after that.

1. Why do we write integration tests?
   A huge friction point in software is how the software will behave in a given environment. So we not only need to test each little functionality but general behaviours.

2. What problems do integration tests solve?
   It solves how the software will behaves in a production environment. An integration test suite try to replicate as much as possible the production environment.

3. What are the differences between top-down and bottom-down approaches?
   The main difference is the order in which test are run and written. The top-down approach seeks to test component interactions first, then fix each little functionnality. The bottom-down approach start with the little functionalities, then test greater interactions between components.

[Bulky]

1. Why do we write integration tests?
   We want to know and mitigate problems with the interfaces among program components before trouble occurs in real-world program execution.
2. What problems do integration tests solve?
   it mimics scenario’s it will encounteer in “customers” computers,systems and networks
3. What are the differences between top-down and bottom-down approaches?
   bottom-up: begins with unit testing, followed by tests of the higher-level combinations of units, called modules or builds
   top-down: the highest-level modules are tested first and then lower-level modules after that.

I’m being asked to supply my details before I can read the article.
How about, no?
At least not until others can verify what’s going on here.
Can anyone advise?
I’d be appreciated.

[T.O.B]

I did my own research on this as the supplied reading assignment asked for personal information to access the article. This is something I’m not entirely comfortable with, but am open to reasons why I should register with them.

Why do we write integration tests?

• This is done after unit testing and before validation testing.
• It’s the combining of the units to test them as a group.

What problems do integration tests solve?

• Any issues from initial unit integration to issues arising in real world applications can hopefully be addressed before actual use.

What are the differences between top-down and bottom-up approaches?

• Bottom up addressed the most base level units first and works on them until the top level applications function as well as they should.
• Top down looks at the issues of the top, integrated modules, and follows them down to the root of any issues.

[EdTunn]

Why do we write integration tests?
It’s a software development that processes which program units are combined and tested as groups in multiple ways.

What problems do integration tests solve?
The test is done to expose problems with the interfaces among program components before trouble occurs in real-world program execution.

What are the differences between top-down and bottom-down approaches?
Bottom-up testing starts with unit testing, followed by tests of progressively higher-level combinations of units called modules or builds. Top-down integration testing, the highest-level modules are tested 1st and moving to lower-level modules, which are tested after that.

[Duende]

1. in order to discover any problems or malleability with the interfaces among program components.
   2.We can discover problems that may occur in the way different programs interact with each other.
2. Bottom up starts from a low level functionality and goes up while to down works vice versa .

[Larsen]

1. Why do we write integration tests? Testing of code reveals issues with all interfaces linking components together.
2. What problems do integration tests solve? Integration tests find error in the application. Testing of all interfacing subsystems to ensure errors are discovered in a real world used of the application.
3. What are the differences between top-down and bottom-down approaches? Top-down starts testing at higher levels of the software and then tests progressively lower levels of the code. Bottom-up starts at the lower level components and proceeds up. Unit testing is preformed before going to top-down approach.

[vic21]

1. It tests all of the components as a single application
2. It solves problems that may arise from components not functioning as a single unit
3. Top-down involves designing the overall application as a whole, then designing the individual units. Bottom-down involves designing the individual units then getting these units to work together.

[Jones]

1.to expose problems that can be solve before launching the app in the real-world.
2. they solve problems of interactions between different components
3. bottom-up integration starts with units test followed by tests of of progressively higher-level combinations of units called modules or builds.
In top-down integration testing, the highest-level modules are tested first and progressively lower-level modules are tested after that.

[JdRoberts]

1. Tests are written to reveal problems within the interfaces among the components to prohibit real world program execution.
2. They reveal problems between systems and interfaces among program components.
3. Top-down starts testing at higher levels of the software and then tests progressively lower and lower levels of the code. Bottom-up starts at the bottom or low level components and works its way up.

[Daniel_Jude]

1. Integration testing is conducted to evaluate the compliance of a system or component with specified functional requirements.

2. Integration testing fixes issues and ensure that the application as a whole, works as expected.

3. The top-down approach goes from the general to the specific, and the bottom-up approach begins at the specific and moves to the general.

[Vikthor]

Why do we write integration tests?

• exposing problems with the interfaces among program components / between multiple programs or applications.

What problems do integration tests solve?

• Find problems with the way different program components interact with each other.

What are the differences between top-down and bottom-up approaches?

• The bottom-up process starts with unit testing followed by higher level tests.
  In top-down integration testing you test higher levels first and than go down to units.

[Apex]

1. it guarantee the smooth operation of the software.

2. expose problems with the interfaces among program components before trouble occurs in real-world program execution. Integration testing is a component of extreme programming, a pragmatic method of software development that takes a meticulous approach to building a product by means of continual testing and revision.

3. Bottom-up integration testing begins with unit testing followed by tests of of progressively higher-level combinations of units called modules or builds. In top-down integration testing, the highest-level modules are tested first and progressively lower-level modules are tested after that.

[lordkalvin]

• Why do we write integration tests?
  • To ensure code operates as intended
• What problems do integration tests solve?
  • problems with the interfaces among program components
• What are the differences between top-down and bottom-down approaches?
  • Bottom-up integration testing:
    - begins w/unit testing, followed by tests of of progressively higher-level combinations of units called modules or builds
  • Top-Down integration testing:
    - begins w/highest lvl module testing, followed by tests of progressively lower-level modules
  • Bottom-Down integration testing:
    - Doesn’t exist. [answered in case of intentional trick-question]

[LioC]

1/ for checking good processing of appli
2/ interfacing between modules of appli
3/ top-down: you first test high-level functionalities, and progressively go testing under-levels
bottom-down:???
did you mean bottom-up?

[Ana.Barreto]

[Iman_Imano]

1). To test programs in relation to themselves and other interfaces.

2. The functionality of the program in different scenarios are tested on a larger scale and unit scale and with different modalities.

3. Bottom up starts the test with the unit level and works its way up to larger code combinations until it comes to the top level whole program. The top down starts at the larger combos and goes down until it gets to the unit level program.
