# jest-test-cases
Utility library that facilitates test-case-driven development.
## Description
`describeTestcase` helps you highlight the essence of a test: inputs and outputs. Focus on coming up with more test cases, and let the library do the assertions for you.
```ts
function toCamelCase(s: string) {
// ...
}
describeTestcase("utils/toCamelCase", toCamelCase, {
testCases: [
{
should: "return an empty string",
given: "an empty string",
cases: { input: "", expected: "" }
},
{
should: "transform input to camel case strings",
given: "a non-empty string",
cases: [
{ input: "Hello world", expected: "helloWorld" },
{ input: "word", expected: "word" },
{ input: "camelCased", expected: "camelCased" }
]
}
]
})
```
Instead of:
```ts
describe("utils/toCamelCase", () => {
it("should return an empty string given an empty string", () => {
expect(toCamelCase("")).toEqual("");
})
it("should transform input to camel case strings given a non-empty string", () => {
expect(toCamelCase("Hello World")).toEqual("helloWorld");
expect(toCamelCase("word")).toEqual("word");
expect(toCamelCase("camelCased")).toEqual("camelCased");
})
})
```
