Assertions are statements in a test that check whether a condition is true — verifying that the actual result matches the expected result. They're the core of how tests determine pass or fail: if an assertion fails, the test fails.
What assertions do
An ASSERTION checks that something is as expected:
→ "assert that the actual value EQUALS the expected value"
→ if TRUE → the assertion passes; if FALSE → the assertion FAILS → the TEST FAILS
→ Assertions are how a test VERIFIES behavior (the "check" part of a test).
