I'm grappling with how to simulate the following functionality. I need to simulate both methods: getAllBookInCategory, deleteBookInCategory
The public method invokes private methods and I presume I don't need to test private methods, only calling public methods and confirming that private methods are called. Is my understanding correct?
public methods: getAllBookInCategory, deleteBookInCategory
private method: makeRequest
import rp from "request-promise-native";
export class BookService {
@param bookCategory id of book category
@param boooks list of books
public static async getAllBookInCategory(bookCategory: string) {
try {
const neededInfo = {
url: `https://${process.env.BOOK_HOST}/bookapi/${process.env.BOOKAPI_VERSION}/iterative/bookCategory/${ bookCategory }/books/all `,
method: 'GET',
}
const result = await BookService.makeRequest(bookCategory, neededInfo);
return rp(result);
} catch(error) {
Console.log(`Failed to get All Books in given category ${error}`)
}
}
public static async deleteBookInCategory(bookCategory: string, books: string[]) {
try{
const neededInfo = {
url: `https://${process.env.BOOK_HOST}/bookapi/${process.env.BOOKAPI_VERSION}/ iterative /bookCategory/${ bookCategory }/books/bookDelete?books=${books.join()}`,
method: 'DELETE',
}
const result = await BookService.makeRequest(bookCategory, neededInfo);
return rp(result);
} catch(error) {
Console.log(`Failed to delete books from category: ${error}`)
}
}
private static async makeRequest(bookCategory: string, neededInfo: any, bodydata?: any) {
const authValue = await BookService.getAuthValue(bookCategory, neededInfo);
return {
method: neededInfo.method,
url: neededInfo.url,
headers: {
Host: process.env.BOOK_HOST,
Authorization: authValue,
},
body: bodydata,
json: true
};
}
}
