The file is copied to the container asynchronously, so we need to wait for it to be available. We can do this by using the waitUntilFileExists method:16public class FileOperationsTest {17    public GenericContainer container = new GenericContainer("alpine:3.8")18            .withCommand("tail", "-f", "/dev/null")19            .withFileSystemBind("src/test/resources", "/test-classes", BindMode.READ_ONLY)20            .waitingFor(Wait.forLogMessage(".*Copied 1 files.*\\n", 1));21    public void testCopyFileFromContainer() throws IOException {22        FileOperations fileOperations = new FileOperations(container.getDockerClient(), container.getContainerId());23        String fileContent = fileOperations.readFile("/test-classes/test.txt");24        assertEquals("test file content", fileContent);25    }26}
