Testing

Tests are an important part of the application. And testing a bot can be extremely simple:

    dependencies {
        ...
        testImplementation("io.github.dehuckakpyt.telegrambot:telegram-bot-test:0.10.3")
    }

Example in code with database storing.

Examples:

com/example/myproject/handler/RegistrationHandlerIT.kt

            @SpringBootTest
            @EnableTelegramBotTest
            class RegistrationHandlerIT @Autowired constructor(
                private val bot: TelegramBot,
            ) {
                @BeforeEach
                fun setUp() {
                    clearAllMocks()
                }
                @Test
                @DataSet("/datasets/handler/registration/command.json")
                @ExpectedDataSet("/datasets/handler/registration/command__expected.json")
                fun `register command`() = runTest {
                    // Arrange
                    coEvery { bot.sendMessage(1_001, any(), replyMarkup = any()) } returns mockk()

                    // Assert
