About The Project
This is a solution to React frontend testing. This package provides a class, ComponentTestHelper, to be used in Jest React frontend testing use cases. This class allows the developer to abstract a lot of the tedious, duplicated, testing that often occurs when attempting to test the frontend, into reusable functions contained within the bounds of a given components "test helper".

import ComponentTestHelper from 'component-test-helper'
define instance for the component to test in the test file
// with a builder
const inputField = new ComponentTestHelper(builder =>
builder.byTestId('inputFieldContainer')
)
// with a custom ComponentTestHelper - builder only necessary if a custructor wasn't supplied
const inputField = new InputFieldTestHelper(builder =>
builder.byTestId('inputFieldContainer')
)
// custom with supplied constructor
const inputField = new InputFieldTestHelper()
define custom ComponentTestHelper in another file
export class InputFieldTestHelper extends ComponentTestHelper {
// define child components to test
readonly input = new ComponentTestHelper(builder =>
builder.byTestId('inputField')
)
// create constructor if you want to hard code the selector for the builder
constructor() {
super(builder => builder.byTestId('inputFieldContainer'))
}
// define methods for acting and expecting on components
async expectToHaveValue(value: string | number | null): Promise<void> {
expect(await this.input.get()).toHaveValue(value)
}
}
