java.lang.IllegalArgumentException: Invalid connection string. Выбрасывает исклчение при тестировании юнит тестом и мокито

Для начала покажу вам методы которые я хочу протестировать, это AzureService

@Service
public class AzureCloudStorageService implements FileService {
    private final String connectionString;
    private final String containerName;
    private final ModelMapper modelMapper;

    public AzureCloudStorageService(@Autowired PropertyResolver propertyResolver,
        ModelMapper modelMapper) {
        this.connectionString = propertyResolver.getProperty("azure.connection.string");
        this.containerName = propertyResolver.getProperty("azure.container.name");
        this.modelMapper = modelMapper;
    }
    public String upload(MultipartFile multipartFile) {
        final String blob = UUID.randomUUID().toString();
        BlobClient client = containerClient()
            .getBlobClient(blob + multipartFile.getOriginalFilename());
        try {
            client.upload(new BufferedInputStream(multipartFile.getInputStream()), multipartFile.getSize());
        } catch (IOException e) {
            throw new NotSavedException(ErrorMessage.FILE_NOT_SAVED);
        }
        return client.getBlobUrl();
    }

    private BlobContainerClient containerClient() {
        BlobServiceClient serviceClient = new BlobServiceClientBuilder()
            .connectionString(connectionString).buildClient();
        return serviceClient.getBlobContainerClient(containerName);
    }

Сейчас покажу мою попытку затестировать это, так как тут не нужно ничего особеного мокать, я думал что если вызвать и сравнить сам метод, то все отлично заработает. В коментариях это то что я думал, что надо создать, но думаю оно не нужно

@Test
    void upload() {
//        azureCloudStorageService.upload(multipartFile);
//        String blob = UUID.randomUUID().toString();
//        BlobServiceClient serviceClient = new BlobServiceClientBuilder()
//                .connectionString(connectionString).buildClient();
//        BlobContainerClient blobContainerClient1 = serviceClient.getBlobContainerClient(containerName);
//        BlobClient client = blobContainerClient1
//                .getBlobClient(blob + multipartFile.getOriginalFilename());
        String expected = "image";
        MultipartFile multipartFile = ModelUtils.getFile();
        String actual = azureCloudStorageService.upload(multipartFile);
        assertEquals(expected, actual);

Ну и сам уже Stacktrace
