Consistent Testing electron-settings

Consistent Testing electron-settings

TL;DR: Delete the settings file before starting the test. Today I implemented a simple wrapper over the electron-settings functionality to gibe me access to a set of properties via get/set methods. My scenario is simple: I have a property named path.backup and I want to be able

Poor Man's Mocks in TypeScript

Poor Man's Mocks in TypeScript

Today I went against my better judgement of usign a mock framework and decided to create my own mocks to allow coverage testing for an IPC-calling code. My reference code I wanted to test is: export class ScanTriggerEvent { name: string = 'scan' constructor(private pathService: PathsService) {} /** * Send a scan

Use "toThrowError" and "toThrow" in TypeScript with Objects

Use "toThrowError" and "toThrow" in TypeScript with Objects

TL;DR: wrap your method call in the expect() statement. Instead of expect(obj.method()).toThrow(), write expect( () => { obj.method() }).toThrow(). While in the process of improving the code coverage, I needed to write a test for a method throwing an exception. My initial code would have been something

Access Data Files for Local Tests in Android

Access Data Files for Local Tests in Android

TL;DR: Put your data files in test/resources and access it with: InputStream inputStream = this.getClass() .getClassLoader() .getResourceAsStream(path); I've got an android application with a module performing data processing (HTML scraping in fact). This part is pure java and all its tests are in the src/

Manually Create a Retrofit/OkHttp Response for Testing

I've got a method in an use case which requires a Retofit Response object as parameter and I need to test it. Now, I can use the Retrofit itself and build one with the network, but it would require the full android shebang. I've opted instead

MVP in Android - A Summary

These days I'm reading on architectures. I had a look at MVC, MVP, MVVM and how they are applied (adapted to?) to Android applications. Here are some short points about MVP. Model-View-Presenter has been adapted to Android and is advocated by more experienced people than I. It is

Android: Provide Local Asset in Testing

Android: Provide Local Asset in Testing

In the past few days I had a little bit of a problem: InstrumentationTestCase gives access to local assets while AndroidTestCase gives access to getAssets() for assets specific to testing. I had a scenario to test where I get a file from my local src/androidTest/assets directory while the
