For this assignment, you will write tests for a SortableTable
component. The implementation for this component will be provided separately. Create the file SortableTable.test.js
with the following tests:
src/SortableTable.test.js
import { render, fireEvent } from "@testing-library/react";
import SortableTable from "./SortableTable";
const columns = [
{
field: "title",
header: "Title",
},
{
field: "score",
header: "Score",
},
];
const rows = [
{ title: "Post A", score: 5 },
{ title: "Post B", score: 3 },
{ title: "Post D", score: 9 },
{ title: "Post E", score: 8 },
{ title: "Post C", score: 1 },
];
test("the table headers", () => {
render(
<SortableTable rows={rows} columns={columns} defaultSort="score:desc" />
);
// You should have at least 2 assertions
// Verify that the Title table header renders "Title"
// Verify that the Score table header renders "Score (desc)"
});
test("rendering rows with a numeric field default sort in ascending order", () => {
render(
<SortableTable rows={rows} columns={columns} defaultSort="score:asc" />
);
// You should have at least 6 assertions
// Verify that the table rows are rendered in the correct order
// Verify that the correct table header has the correct sort direction
});
test("rendering rows with a numeric field default sort in descending order", () => {
render(
<SortableTable rows={rows} columns={columns} defaultSort="score:desc" />
);
// You should have at least 6 assertions
// Verify that the table rows are rendered in the correct order
// Verify that the correct table header has the correct sort direction
});
test("rendering rows with a string field default sort in ascending order", () => {
render(
<SortableTable rows={rows} columns={columns} defaultSort="title:asc" />
);
// You should have at least 6 assertions
// Verify that the table rows are rendered in the correct order
// Verify that the correct table header has the correct sort direction
});
test("rendering rows with a string field default sort in descending order", () => {
render(
<SortableTable rows={rows} columns={columns} defaultSort="title:desc" />
);
// You should have at least 6 assertions
// Verify that the table rows are rendered in the correct order
// Verify that the correct table header has the correct sort direction
});
test("clicking on a table header with the sort reverses the sort", () => {
render(
<SortableTable rows={rows} columns={columns} defaultSort="title:desc" />
);
// You should have at least 12 assertions
});
test("clicking on a table header without the sort applies an ascending sort to that column", () => {
render(
<SortableTable rows={rows} columns={columns} defaultSort="title:desc" />
);
// You should have at least 12 assertions
});
All your tests should pass. I have already included data-testid
attributes on all the elements that you'll need to access in your tests in the provided implementation of SortableTable
.
