Getting to Know Describe & Context

RSpec’s describe and context blocks are used to organize your test suite and provide a clear and concise structure for your tests.

The describe block is used to group related tests together and provides a description of the behavior being tested. It can be used to describe a class, module, or any other component of your application. For example:

describe MyClass do
  # tests go here
end

The context block is used to provide additional context or conditions for the tests being described. It’s often used to describe different scenarios or use cases that you want to test. For example:

describe MyClass do
  context "when initialized with valid arguments" do
    # tests for valid arguments go here
  end

  context "when initialized with invalid arguments" do
    # tests for invalid arguments go here
  end
end

Here, we’re using two context blocks to describe two different scenarios: one where the arguments passed to MyClass are valid, and one where they’re invalid.

By using describe and context blocks in your RSpec tests, you can provide a clear structure for your tests and make it easier to understand what behavior you’re testing and under what conditions.
