Software Testing :

Software Testing is the process of finding bugs in the software and verifying its functionality against the client’s requirements.
It ensures that the software functions as expected and meets the specified requirements before deployment.
Execution of a program with the indent of finding bugs is called software testing.
Testing can be manual or automated, and it plays a crucial role in maintaining software quality.
Software testing is done to improve the quality of the software

Why is Software Testing Important?

Ensures Quality: Testing helps detect bugs early, preventing faulty software from reaching users.

Reduces Cost: Fixing issues during development is cheaper than post-release fixes.

Improves User Satisfaction: A well-tested product provides a smooth user experience.

Ensures Compliance: Helps meet regulatory or security standards.

Example: Imagine using a banking app that fails during a money transfer. Testing prevents such issues by checking for errors beforehand.

Types of Testing :

Manual Testing : Performed by a tester manually without using any automation tools.

Example: Checking if the login button on a website works properly by manually entering different credentials.

Automation Testing : Uses tools to run tests automatically and repeatedly.

Example: Using Selenium to check if an e-commerce site correctly displays product prices every time the page loads.

Profiles of Testing:

White Box Testing: Done by developers. It involves checking the internal code and logic.

Example: Verifying that a loop runs exactly 5 times in a piece of code.

Black Box Testing: Done by testers without knowing the code. Focuses on input and output.

Example: Entering a valid username and password and checking if the user logs in successfully.

Grey Box Testing: Combination of both white and black box testing.

Levels of Testing :

Unit Testing: Tests individual components.
Example: Testing a calculator’s Add function alone.

Integration Testing: Ensures different modules work together.
Example: Ensuring the login and dashboard work smoothly together.

System Testing: Tests the complete system as a whole.
Example: Running tests on the full website to ensure everything functions.

User Acceptance Testing (UAT): Ensures the software meets user expectations.
Example: A client tries the software and approves it for use.

Performance Testing: Testing the stability and response time of an application.
Example: You're testing an online shopping website during a festive sale.
*Does the site load within 2 seconds?
*Does it crash or slow down when multiple people place orders?
*Is the payment gateway responsive under load?
This helps ensure the website performs well even during traffic spikes.

Smoke Testing: Testing the basic functionality of an application.
Example: Checking log in functionality using valid credentials.

Functional vs Non-Functional Testing

Functional Testing: Checks what the system does.

Example: Verifying if the search bar returns correct results.

Non-Functional Testing: Checks how the system performs.

Example: Measuring how fast a website loads during peak hours.

Bug and Defect

Defect: A deviation from expected requirements.

Bug: Informal term for defect found during testing.

Software Testing Life Cycle (STLC):

1.Requirement Analysis

2.Test Planning

3.Test Case Development

4.Test Environment Setup

5.Test Execution

6.Test Closure

Bug Life Cycle :

New - Open - In Progress - Fixed - Retest - Closed/Reopened

Testing Tools :

Automation: Selenium

Defect Tracking: JIRA

Conclusion :

Software Testing is not just about finding bugs. It ensures the final product is reliable, performs well, and provides a good user experience. Whether done manually or through automation, testing plays a key role in building trust with users and stakeholders.

Problem solving TASK - 2

Danielprem — Tue, 12 Nov 2024 06:09:49 +0000

1. Total number of vowels and count of each vowel in the given string

text = "Guvi Geeks Network Private Limited"
vowels = {'A':0,'E':0,'I':0,'O':0,'U':0}
text = text.upper()

for i in text:
if i in vowels:
vowels[i] += 1

total_vowels = sum(vowels.values())

print("Count of each vowel : ",vowels)
print("Total number of vowels : ",total_vowels)

2. Pyramid of numbers from 1 to 20 using for loop

n = 20
strt = 1
rows = 6

for i in range(1,rows + 1):
for j in range(i):
if strt <= n:
print(strt, end=" ")
strt += 1
else:
break
print()

3. Write a program that takes a string and returns a new string with all the vowels removed

oldstr = input("Enter the string: ")
vowels1 = ('a','e','i','o','u')
oldstr = oldstr.lower()
newstr = ""

for i in oldstr:
if i not in vowels1:
newstr += i

print("Non-vowel string : ",newstr)

4. Write a program that takes a string and returns the number of unique characters in it

str2 = input("Enter the string: ")
str2 = str2.lower()
str2 = str2.replace(" ","")
myset = set(str2)
print("number of unique characters :" ,len(myset))

5. Write a program that takes a string and returns true if it is a palindrome or false otherwise

mystr = input("Enter the string: ")
mystr = mystr.lower().replace(" ","")
rev_mystr = mystr[::-1]
if mystr == rev_mystr:
print(True)
else:
print(False)

7. Write a program that takes a string and returns the most frequent character in it

txt = input("Enter the string: ")
txt = txt.lower().replace(" ","")
frequency = {}

for i in txt:
if i not in frequency:
frequency[i] = 1
else:
frequency[i] += 1

max_char = max(frequency,key=frequency.get)
print("Most frequent character:",max_char)

8. Write a program that takes a string and returns true if its an anagram of another string or false otherwise

str_x = input("Enter the string: ")
str_y = input("Enter the another string: ")
str_x = str_x.lower().replace(" ","")
str_y = str_y.lower().replace(" ","")
sorted_x = sorted(str_x)
sorted_y = sorted(str_y)
if sorted_x == sorted_y :
print(True)
else:
print(False)

9. Write a program that takes a string and returns the number of words in it

str1 = input("Enter the string: ")
str = str1.split()
print("Number of words :",len(str))

Software Testing is the process of finding bugs in the software and verifying its functionality against the client’s requirements.

We must know the purpose , types and methodologies of software testing to acquire essential information about the role and aspects of a software tester.

Software testing is relevant to ensure and improve the quality of the software and to check the stability and its performance according to client’s expectations.
