📝 Walkthrough

Walkthrough

Adds a new Label atom (component and props) and two test suites: one for the Label atom and one for the Header layout component, covering rendering, prop wiring, conditional UI, and user interaction behaviors.

Changes

Cohort / File(s) Summary
Label component & types
src/components/atoms/Label/Label.tsx, src/components/atoms/Label/LabelProps.ts
New default-exported Label component plus LabelProps/LabelSize types. Supports htmlFor, required indicator (visible * and screen-reader text), size variants, disabled styling, and className merging.
Component tests
src/components/atoms/Label/Label.test.tsx, src/components/layout/Header/Header.test.tsx
New tests: Label tests cover rendering, htmlFor wiring, and required indicator presence/absence; Header tests cover banner/title, first nav link/href, profile button/avatar rendering and alt fallback, and onLogout invocation via click.

🤖 Fix all issues with AI agents
In @src/components/atoms/Label/Label.test.tsx:
- Around line 6-10: The test in Label.test.tsx uses a non-semantic name and
query: rename the spec for the Label component to start with "should" (e.g.,
"should render the label text for the associated control") and replace
screen.getByText("Email Address") with an accessibility-focused query such as
screen.getByLabelText or screen.getByRole (targeting the associated input/role
by accessible name) to assert the label is tied to the control; apply the same
naming and semantic-query changes to the other tests referenced (lines 12-17,
19-27, 29-33) so all tests use "should" prefixes and prefer
getByLabelText/getByRole over getByText.

In @src/components/layout/Header/Header.test.tsx:
- Around line 13-16: Rename the test titles to start with "should" and make them
descriptive: e.g., change it("renders the navbar container", ...) to it("should
render the navbar container", ...) and similarly update the other test
descriptions around the Header component tests that call render(<Header
{...defaultProps} />) and assertions like
expect(screen.getByRole("banner")).toBeInTheDocument(); and the tests that check
links, buttons, and conditional items; keep the test bodies unchanged, only
update the string descriptions for lines mentioned (and the other ranges) so all
test names begin with "should".
- Around line 48-55: The test should use async/await with userEvent instead of
fireEvent: make the test callback async, replace fireEvent.click(profileButton)
with await userEvent.click(profileButton), and ensure userEvent is imported (or
available) in Header.test.tsx so the user interaction is simulated realistically
when asserting mockLogout in the "calls onLogout when profile button is clicked"
test.
- Line 1: Replace the use of fireEvent with @testing-library/user-event: update
the import line to import userEvent (instead of fireEvent) alongside render and
screen, then replace occurrences of fireEvent.* in Header.test.tsx with the
corresponding userEvent.* calls (e.g., userEvent.click) and make the test
async/await where necessary to account for userEvent's async behavior so
interactions behave like real users.
🧹 Nitpick comments (3)
src/components/atoms/Label/Label.test.tsx (1)

5-34: Add missing test coverage for accessibility and edge cases.

Based on learnings, tests should include coverage for: default props, variants, accessibility. Consider adding tests for:

  • Accessibility: verify the label element has proper ARIA attributes
  • Default behavior: test without htmlFor prop
  • Class names/styling variants (if applicable)
  • Empty or undefined children
📝 Example additional tests
it("should be accessible without htmlFor attribute", () => {
    render(<Label>Label without htmlFor</Label>);
    
    const label = screen.getByText("Label without htmlFor");
    expect(label.tagName).toBe("LABEL");
});

it("should handle empty children gracefully", () => {
    render(<Label htmlFor="test" />);
    
    const label = screen.getByLabelText("", { selector: 'label' });
    expect(label).toBeInTheDocument();
});
src/components/layout/Header/Header.test.tsx (2)

23-27: Use more specific query instead of index-based selection.

Using getAllByRole("link")[0] is brittle. Consider using a more specific query with name option or getByRole("link", { name: /menu/i }) to target the specific link.

♻️ More specific query example
     it("should render the hamburger menu link", () => {
         render(<Header {...defaultProps} />);
-        const menuLink = screen.getAllByRole("link")[0];
+        const menuLink = screen.getByRole("link", { name: /menu|hamburger/i });
         expect(menuLink).toHaveAttribute("href", "/");
     });

Note: Adjust the regex pattern based on the actual accessible name of the hamburger menu link.


29-32: Use more specific query when multiple buttons exist.

getByRole("button") may be ambiguous if the Header contains multiple buttons. Consider using getByRole("button", { name: "..." }) or a more specific query to target the exact button.

♻️ More specific query example
     it("should render profile button", () => {
         render(<Header {...defaultProps} />);
-        expect(screen.getByRole("button")).toBeInTheDocument();
+        expect(screen.getByRole("button", { name: /profile|logout/i })).toBeInTheDocument();
     });

     it("should call onLogout when profile button is clicked", async () => {
         render(<Header {...defaultProps} />);
-        const profileButton = screen.getByRole("button");
+        const profileButton = screen.getByRole("button", { name: /profile|logout/i });
 
         await userEvent.click(profileButton);
 
         expect(mockLogout).toHaveBeenCalledOnce();
     });

Note: Adjust the name pattern based on the actual accessible name of the profile button.

In @src/components/layout/Header/Header.test.tsx around lines 48 - 55, The test
should use async/await with userEvent instead of fireEvent: make the test
callback async, replace fireEvent.click(profileButton) with await
userEvent.click(profileButton), and ensure userEvent is imported (or available)
in Header.test.tsx so the user interaction is simulated realistically when
asserting mockLogout in the "calls onLogout when profile button is clicked"
test.

Pull request overview

This PR introduces test suites for two components following Test-Driven Development (TDD) practices: a new Label atom component and the existing Header layout component. The tests are written first, with the Label component implementation to follow (TDD Red phase).

Key Changes

  • Added comprehensive test coverage for the Label atom component covering rendering, htmlFor attribute binding, and required indicator behavior
  • Added test suite for the Header component validating navigation elements, user profile rendering, and logout functionality

Reviewed changes

Copilot reviewed 2 out of 3 changed files in this pull request and generated 7 comments.

According to the project's testing standards, test descriptions should start with "should" for consistency. For example: "should render the navbar container" instead of "renders the navbar container". This pattern is established in the coding guidelines and helps maintain a consistent AAA (Arrange-Act-Assert) testing pattern throughout the project.

Using getAllByRole with array indexing [0] is fragile and can lead to brittle tests. Instead, use a more specific query that uniquely identifies the hamburger menu link, such as checking for the specific link that contains the SVG icon or using a more descriptive role query. Consider using getByRole('link', { name: /menu/i }) if the link has accessible text, or add a test-id if necessary as a last resort.

According to the project's coding guidelines, fireEvent should be replaced with userEvent from '@testing-library/user-event' for more realistic user interaction simulation. The guidelines specifically state "Use @testing-library/user-event for user interactions" and "Always use async/await with user events".

The code should be:

const user = userEvent.setup();
await user.click(profileButton);

Note that the test function would also need to be made async.

The test file is missing the import for userEvent from '@testing-library/user-event', which is needed for proper user interaction testing according to the project's coding guidelines. Add the import:

import userEvent from '@testing-library/user-event';

This is required for following the guideline: "Use @testing-library/user-event for user interactions".

The import statement uses a default import, but based on the project's coding guidelines, components should be exported as named exports, not default exports. This should be:

In @src/components/atoms/Label/Label.tsx:
- Around line 26-33: The required asterisk in Label.tsx is hidden from screen
readers (span with aria-hidden="true") but there is no accessible indication of
required fields; when props.required is true, keep the visual asterisk (span
aria-hidden="true") and add a sibling screen-reader-only element (e.g., a span
with a "sr-only" class or aria-label text) that reads "required" for assistive
tech; update the Label component's tests to assert that the accessible
"required" text exists when props.required is true (reference props.required,
the existing aria-hidden span, and the Label component).
- Around line 10-11: The component currently uses a default export and raw
props; change it to a named export "export function Label" and destructure
incoming props (e.g., { size = "md", ... } : LabelProps) so size defaulting
happens in the parameter list instead of inside the function, and add a JSDoc
block above the function including a brief description and an @example showing
typical usage (using the Label and size prop) so the component follows
guidelines; keep the LabelProps type reference in the JSDoc and update any
imports/exports that relied on the default export to use the named export.

1-24: LGTM!

The props file follows the coding guidelines correctly:

  • Uses type for the union (LabelSize)
  • Uses interface for the object shape (LabelProps)
  • Includes JSDoc comments for all props
  • Correct naming convention with PascalCase and Props.ts suffix

15-22: Class construction follows guidelines.

Good use of the array and .filter(Boolean).join(" ") pattern for dynamic class names as specified in the coding guidelines.

🛠️ Refactor suggestion | 🟠 Major

Use named export and add JSDoc documentation.

Per coding guidelines, components should use named exports and include JSDoc comments with @example tags.

- Around line 5-34: Tests for the Label atom are missing coverage for default
props, size variants, disabled state, custom className and accessibility; update
src/components/atoms/Label/Label.test.tsx to add tests that render the Label
component and assert its role and classes: use render(<Label ... />) and
screen.getByRole('label', { name: /email/i }) to verify the default size maps to
the "md" styling (expect class like "text-sm"), verify size="sm" yields
"text-xs" and size="lg" yields "text-base", verify disabled prop adds
"opacity-50" and "cursor-not-allowed", and verify passing className (e.g.
"custom-class") is applied; keep existing tests for text, htmlFor and required

🧹 Nitpick comments (4)
src/components/atoms/Label/Label.test.tsx (4)

6-10: Test name should start with "should".

Per coding guidelines, test names should start with "should" for consistency. Additionally, consider using getByRole('label') instead of getByText for more semantic queries.

♻️ Suggested refactor
-    it("renders the label text correctly", () => {
+    it("should render the label text correctly", () => {
         render(<Label htmlFor="email">Email Address</Label>);
 
-        expect(screen.getByText("Email Address")).toBeInTheDocument();
+        expect(screen.getByRole('label', { name: /email address/i })).toBeInTheDocument();
     });

Based on coding guidelines.


12-17: Test name should start with "should" and use semantic queries.

Use getByRole('label') for more semantic querying of label elements.

♻️ Suggested refactor
-    it("applies the htmlFor attribute correctly", () => {
+    it("should apply the htmlFor attribute correctly", () => {
         render(<Label htmlFor="email">Email</Label>);
 
-        const label = screen.getByText("Email");
+        const label = screen.getByRole('label', { name: /email/i });
         expect(label).toHaveAttribute("for", "email");
     });

Based on coding guidelines.


19-27: Test accessibility features rather than implementation details.

The test checks for the asterisk "*", which is an implementation detail. Per coding guidelines, tests should verify behavior and accessibility features. Consider testing for the screen-reader text "(required)" or aria attributes instead.

♻️ Suggested refactor
-    it("shows required indicator when required prop is true", () => {
+    it("should show required indicator when required prop is true", () => {
         render(
             <Label htmlFor="email" required>

             </Label>
         );
 
-        expect(screen.getByText("*")).toBeInTheDocument();
+        expect(screen.getByText("(required)")).toBeInTheDocument();
     });

Based on coding guidelines.


29-33: Test name should start with "should".

Update the test name to follow coding guidelines. Also consider testing for the absence of the screen-reader text "(required)" instead of the asterisk.

♻️ Suggested refactor
-    it("does not show required indicator when required is false", () => {

🛠️ Refactor suggestion | 🟠 Major

Add missing test coverage for variants, disabled state, default props, and accessibility.

Per coding guidelines, component tests must include coverage for default props, variants, disabled state, and accessibility. The Label component has a size prop with variants ("sm", "md", "lg"), a disabled prop, and a default size of "md", but these are not tested.

📋 Suggested additional tests

Add the following test cases to ensure complete coverage:

it("should apply default size (md) when no size prop is provided", () => {
    render(<Label htmlFor="email">Email</Label>);
    const label = screen.getByRole('label', { name: /email/i });
    expect(label).toHaveClass('text-sm'); // md size maps to text-sm
});

it("should apply small size styling", () => {
    render(<Label htmlFor="email" size="sm">Email</Label>);
    const label = screen.getByRole('label', { name: /email/i });
    expect(label).toHaveClass('text-xs');
});

it("should apply large size styling", () => {
    render(<Label htmlFor="email" size="lg">Email</Label>);
    const label = screen.getByRole('label', { name: /email/i });
    expect(label).toHaveClass('text-base');
});

it("should apply disabled styling when disabled prop is true", () => {
    render(<Label htmlFor="email" disabled>Email</Label>);
    const label = screen.getByRole('label', { name: /email/i });
    expect(label).toHaveClass('opacity-50');
    expect(label).toHaveClass('cursor-not-allowed');
});

it("should apply custom className", () => {
    render(<Label htmlFor="email" className="custom-class">Email</Label>);
    const label = screen.getByRole('label', { name: /email/i });
    expect(label).toHaveClass('custom-class');
});

Based on coding guidelines.

In @src/components/atoms/Label/Label.test.tsx around lines 5 - 34, Tests for the
Label atom are missing coverage for default props, size variants, disabled
state, custom className and accessibility; update
src/components/atoms/Label/Label.test.tsx to add tests that render the Label
component and assert its role and classes: use render(<Label ... />) and
screen.getByRole('label', { name: /email/i }) to verify the default size maps to
the "md" styling (expect class like "text-sm"), verify size="sm" yields
"text-xs" and size="lg" yields "text-base", verify disabled prop adds
"opacity-50" and "cursor-not-allowed", and verify passing className (e.g.
"custom-class") is applied; keep existing tests for text, htmlFor and required
indicator and ensure assertions use toHaveClass / toHaveAttribute /
toBeInTheDocument as appropriate.
