Pseudo Code and Testing Concepts

Pseudo Code Execution

• The provided pseudo code snippet will print "Hello, world" five times.
• This is achieved by a WHILE loop that continues as long as the variable count is less than or equal to 5.
• Inside the loop, the statement print "Hello, world" is executed, followed by incrementing count by 1.

Non-Functional Requirements Testing

• Non-functional requirements are typically tested during System Testing.
• System Testing focuses on evaluating the system as a whole, including its performance, scalability, security, and usability.

Menu Display Using Control Structure

• A Do-While loop is suitable for ensuring a menu is displayed at least once before performing operations.
• This loop executes the code block within it at least once, and then checks the condition. If the condition is true, the loop repeats; otherwise, it terminates.

Feature Driven Development Phases

• The two phases of Feature Driven Development (FDD) that are repeated until all features are developed are: Plan by Feature and Build by Feature.
• Plan by Feature involves breaking down the features into smaller tasks, while Build by Feature focuses on implementing and testing the features individually.

Public Boolean lookingAt() Method

• The lookingAt() method in Java's regular expression engine (java.util.regex) attempts to match the pattern against the input sequence, starting at the beginning of the input sequence.
• It returns true if the pattern matches partially or fully at the beginning of the input sequence; otherwise, it returns false.

Primary Key and NULL Values

• A primary key cannot have NULL values in a relational database.
• A primary key is a column or set of columns that uniquely identify each row in a table, and NULL represents an unknown or missing value.

Outer Join vs. Inner Join

• An Outer Join includes all rows from one or both tables, even if there are no matching values in the other table.
• An Inner Join only returns rows where there are corresponding values in both tables.

Metadata in SQL

• Metadata in SQL is referred to as Data Information.
• Metadata provides information about the database itself, such as table names, column names, data types, and constraints.

Agile Software Development

• Agile software development is a conceptual teamwork approach where software is developed iteratively.
• This approach emphasizes collaboration, flexibility, and continuous feedback throughout the development process.

Agile Deliverables

• Many builds or releases are delivered in an agile process.
• Agile development focuses on delivering working software in short increments, allowing for continuous feedback and adaptation to changing requirements.

DSDM - Dynamic System Development Method

• DSDM stands for Dynamic System Development Method.
• DSDM is a rapid application development (RAD) framework that emphasizes user involvement, iterative development, and timeboxing.

BitBucket Features

• Some key features of BitBucket include: Code Review, Pipelines, Build Integrations, Jira Software Integrations, Different Views, and Projects.
• BitBucket also supports integrations with various IDEs.

Code Phase in Agile

• The Code Phase in an Agile process is where the development team translates the user stories into working code.
• Requirements and feedback are gathered throughout the development process from customers and stakeholders, not just during the Code Phase.

Multibranch Pipelines Plugins

• The appropriate functional plugins used in multibranch pipelines for validating pull or charge requests are:
  • GitHub Branch Source for Git repositories hosted on GitHub.
  • BitBucket Branch Source for Git repositories hosted on BitBucket.
• These plugins enable multibranch pipelines to automatically trigger builds and tests based on changes in specific branches.

Programming Fundamentals

• Pseudocode example: A loop that prints "Hello, world" five times.
• Control Structure: A do-while loop is used to ensure a block of code executes at least once before a condition is checked.
• ArithmeticException is thrown when dividing by zero.

Software Development Methodologies

• Feature Driven Development (FDD): "Develop an overall Model" and "Plan By Feature" are repeated until all features are implemented.
• FDD phases: Design by Feature, Build a Features List, Build By Feature
• Agile: Iterative development process where many builds are delivered.
• DSDM: Dynamic System Development Method.
• Agile emphasizes customer feedback and collaboration throughout the development process.

Software Quality

• System Testing: Non-functional requirements are tested at the system testing level.
• Non-functional requirements: Features like performance, security, and usability.
• Functional requirements: Define the system's expected behavior.

Database Concepts

• Outer Join: Used to include rows that may not have matching values in the joined tables.
• Meta Data: Data information in SQL.
• Primary Key: Cannot contain NULL values.

Version Control Systems

• BitBucket: Offers features like Code Review, Pipelines, Build Integrations, Jira Software Integrations, Trello Boards, Different Views, Projects, and IDE Integration.
• Trello Boards: Used for project management and collaboration.

Git and Jenkins

• Multibranch Pipelines: Utilize plugins for automating the validation of pull or charge requests.
• Commonly used plugins: Github Branch Source, Github Main Source, BitBucket Branch Source, BitBucket Main Source.

Java Programming

• lookingAt() Method: Attempts to partially or fully match a pattern within the Matcher object.

Code Snippet Analysis

• Snippet 1: Divides an integer a by i in a loop, printing the result or catching any ArithmeticException. Output includes the quotient for each iteration and the exception message when i is zero.
• Snippet 2: Prints "0" as output. The code snippet initializes an empty array of integers, then attempts to print it. In Java, an empty array will be initialized with a default value of 0.
