Testy jednostkowe
Testy
A software testing method by which individual units of source code, sets of one or more computer program modules together with associated control data, usage procedures, and operating procedures, are tested to determine whether they are fit for use.

Testy
A unit test provides a strict, written contract that the piece of code must satisfy.
A software design technique that emphasizes separating the functionality of a program into independent, interchangeable modules
Testy jednostkowe (unit tests)
24 definitions
- low-level
- written by programmers themselves
- significantly faster than other tests
Testy jednostkowe (unit tests)
Propozycja
- Nie definiujmy testu jednostkowego bez definiowania (wskazania) modułu
- Definicja będzie różna dla różnych przypadków i projektów
Testy integracyjne
Testy
Integration tests determine if independently developed units of software work correctly when they are connected to each other.

Board vs Narrow Integration Tests
Testy systemowe
Testy systemowe (system tests)
System testing is testing conducted on a complete integrated system to evaluate the system's compliance with its specified requirements.
Software testing is an investigation conducted to provide stakeholders with information about the quality of the software product or service under test.
System testing means testing the system as a whole.
Testy akceptacyjne
Testy akceptacyjne (acceptance tests)
An acceptance test is a formal description of the behavior of a software product, generally expressed as an example or a usage scenario.
The terms "functional test", "acceptance test" and "customer test" are used more or less interchangeably.
"Acceptance test" ~ "Acceptance criteria"
Testy akceptacyjne (acceptance tests)
End to end tests
End to end tests
End-to-end testing is a Software testing methodology to test an application flow from start to end.
The purpose of End to end testing is to simulate the real user scenario and validate the system under test and its components for integration and data integrity.
End to end tests
Horizontal vs vertical end to end testing
End to end tests
Vertical end to end test = system test
Horizontal end to end test is more than that (~ User Journey Test)
Piramida testów
Test Pyramid (piramida testów)
Test Pyramid (piramida testów)
- Write tests with different granularity
- unit tests
- integration tests
- system tests
- The more high-level you get the fewer tests you should have
Smoke tests
Smoke tests
A.K.A confidence testing, sanity testing.
Preliminary testing to reveal simple failures severe enough to, for example, reject a prospective software release.
Testy regresyjne
Testy regresyjne (regression tests)
A type of software testing to confirm that a recent program or code change has not adversely affected existing features.
Testy antyregresyjne?!
Zasada: Każdy bug zwieńzczyć testem żeby uniknąć regresji
Black-box tests
White-box tests
Black-box tests
Examines the functionality of an application without peering into its internal structures or workings.
Tests what, not how.
This method of test can be applied virtually to every level of software testing: unit, integration, system and acceptance.
It is sometimes referred to as specification-based testing.
White-box tests
Tests internal structures or workings of an application, as opposed to its functionality
Techniques (examples):
- Code coverage
- Fault injection methods
- Mutation testing methods
Automatyczne testy
Manualne testy
Testy automatyczne / manualne
Unit testing is commonly automated, but may still be performed manually. The IEEE does not favor one over the other.
Zawód testera
Automatyczne testy umożliwiają CI / CD
Testy automatyczne / manualne
Zawód testera
Nie wszystko da się zautomatyzować.
I automatyzacja bywa kosztowna, i niesie ryzyko.
-> automated chaos is still chaos
