Introduction to 'Minitest assert true'

Minitest is a popular Ruby testing framework. It provides a simple and intuitive way to write and run tests for your Ruby code, helping you ensure that your applications work as expected.

One of the most basic assertions that you can make in a Minitest test is the 'assert true' assertion. This assertion simply checks to see if a given statement evaluates to 'true' or not. If it does, the test passes; if not, the test fails.

Syntax

Here's the syntax for using 'assert true' in a Minitest test:

assert(true)

Alternatively, you can use a block to define the statement you want to check:

assert { some_statement }

Example

Let's look at an example of using 'assert true' in a Minitest test:

require 'minitest/autorun'

class MyTest < Minitest::Test
  def test_assert_true
    assert(true)
  end

  def test_assert_block_true
    assert { 1 + 1 == 2 }
  end
end

In the above example, we define a Minitest test class with two test methods: 'test_assert_true' and 'test_assert_block_true'. In each method, we use 'assert true' to check a statement.

The first test simply checks that 'true' is indeed true, and thus passes. The second test defines a block that adds 1 and 1 together, resulting in 2. Since 2 is indeed equal to 2, this test also passes.

Conclusion

In conclusion, 'assert true' is a simple and useful assertion that you can use in your Minitest tests to ensure that a given statement evaluates to true. By using this assertion, you can easily verify that your applications are working as expected.
