PASS/FAIL

This flow shows how Laravel sends an HTTP request, receives a response, and then checks assertions like status code and content to decide if the test passes.

Execution Sample

Laravel

public function test_homepage()
{
    $response = $this->get('/');
    $response->assertStatus(200);
    $response->assertSee('Welcome');
}

This test sends a GET request to '/' and asserts the response status is 200 and the page contains 'Welcome'.

Execution Table

Step	Action	Evaluation	Result
1	Send GET request to '/'	Request sent	Response received
2	Check status code == 200	Status is 200	Pass
3	Check response contains 'Welcome'	'Welcome' found	Pass
4	All assertions passed	Test passes	PASS

💡 Test ends after all assertions pass successfully.

Variable Tracker

Variable	Start	After Step 1	After Step 2	After Step 3	Final
$response	null	HTTP response object	Same	Same	Same
Status Code	N/A	N/A	200	200	200
Response Content	N/A	N/A	N/A	Contains 'Welcome'	Contains 'Welcome'

Key Moments - 2 Insights

Why does assertStatus(200) come before assertSee('Welcome')?

Because checking the status code first ensures the response is valid before looking for content, as shown in steps 2 and 3 of the execution_table.

What happens if the status code is not 200?

The test fails immediately at step 2, so assertSee is not checked, preventing misleading errors.

Visual Quiz - 3 Questions

Look at the execution_table, what is the result of step 3?

A Fail

B Skipped

C Pass

D Error

💡 Hint

Check the 'Result' column for step 3 in the execution_table.

At which step does the test confirm the HTTP status code?

A Step 1

B Step 2

C Step 3

D Step 4

💡 Hint

Look at the 'Action' column in the execution_table for status code check.

If the response did not contain 'Welcome', which step would fail?

A Step 3

B Step 2

C Step 1

D Step 4

💡 Hint

Refer to the 'Action' and 'Result' columns in the execution_table for content check.

Concept Snapshot

Laravel HTTP test assertions:
- Use $this->get('/url') to send request
- Use assertStatus(code) to check HTTP status
- Use assertSee(text) to check response content
- Assertions run in order; failure stops test
- Helps verify your app responds correctly

Full Transcript

In Laravel HTTP test assertions, you send a request using methods like get(). Then you check the response status with assertStatus(). Next, you check if the response contains expected text with assertSee(). The test passes only if all assertions succeed in order. If any assertion fails, the test stops immediately. This helps ensure your web app behaves as expected when accessed.
