What is Test Driven Development (TDD)?

Test Driven Development (TDD) is a type of development with automated tests. It is an approach towards clean code.

Two simple rules of Test Driven Development (TDD) are –

(1) Write new code only if an automated test has failed and (2) Eliminate duplication. These 2 rules are followed by the tasks of programming which are called as TDD mantra (Red/green and refactoring).

Test Driven Development (TDD) Mantra

Red – Start simple with a little test that does not work

Green – Make the test work quickly by making changes to the code

Refactoring – Eliminate dependencies (path to clean code)

According to Kent Beck (author of Test-Driven Development by example), rhythm of TDD is as follows –

  1. Quickly add a test
  2. Run all tests and see the new one fail
  3. Make a little change
  4. Run all tests and see them all succeed
  5. Refactor to remove duplication

Refer this book – Test Driven Development by example by Kent Beck to learn about TDD, he has beautifully explained the concepts with a live example and patterns for TDD.

How to prepare for a scrum master interview?

Preparing for a scrum master interview is no different than preparing for any other interview, having said that the technical questions focus is on Scrum and a bit on agile question and team coaching (if you are an experienced scrum master, be prepared for team coaching skills). Normally an interview can be broadly divided in 4 categories –

  1. General Questions
  2. Technical Questions
  3. Behavioral Questions
  4. Situational Questions

Considering each one of us had a different journey, all your answers should be based on your own experience and the level of knowledge.

Below you will find a list of questions for each of these 4 categories, for some questions you will get the answer and for some we have shared guidance for these questions which will help you prepare for interview. Some questions are pretty straight forward, there are no answers mentioned.

Scaling means making it large, taking it forward to the next level.  Have a look at the agile basics before understanding the scaling agile frameworks. We will divide the framework in 3 categories – (1) Team Level (2) Multiple team level and (3) Enterprise level. Scaling framework is applicable to the last 2 categories – Multiple team and enterprise.
