[英]Test a Camel sFTP endpoint
我有以下路线:
public void configure() throws Exception {
from(ftpEndpoint)
.routeId("import-lib-files")
.log(INFO, "Processing file: '${headers.CamelFileName}' from Libri-FTP")
.choice()
.when(method(isFilenameAlreadyImported))
.log(DEBUG, "'${headers.CamelFileName}' is already imported.")
.endChoice()
.otherwise()
.bean(method(unzipLibFile))
.bean(method(persistFilename))
.log(DEBUG, "Import file '${headers.CamelFileName}'.")
.endChoice()
.end()
.end();
}
在unzipLibFile
处理器 bean 中,来自 ftp 的文件被解压缩并写入 HD。
我想测试(集成测试)这条路线,比如:
我喜欢:
@Before
public void setUp() throws Exception {
// delete test-file from sftp
final String uploaded = ftpPath + "/" + destination + "/libri-testfile.zip";
final File uploadedFile = new File(uploaded);
uploadedFile.delete();
// delete unzipped test-file
final String unzippedFile = unzipped + "/libri-testfile.xml";
final File expectedFile = new File(unzippedFile);
expectedFile.delete();
// delete entries from db
importedLibFilenameRepository.deleteAll();
// copy file to ftp
final File source =
new ClassPathResource("vendors/references/lib.zip/libri-testfile.zip").getFile();
final String target = ftpPath + "/" + destination + "/libri-testfile.zip";
FileUtils.copyFile(new File(source.getAbsolutePath()), new File(target));
}
@Test
@Ignore
public void testStuff() throws Exception {
// Well here is a problem, I can't fix at the moment
// the Camel-Context within the SpringContext get started when the tests starts
// during this process the Camel-Routes are executed and because i copied the file to
// the ftp all is fine... but I don't want to have a sleep in a test, I want to start the
// route (like commented code beneath the sleep)
Thread.sleep(2000);
// final Map<String, Object> headers = Maps.newHashMap();
// headers.put("CamelFileName", "libri-testfile.zip");
//
// final File file =
// new ClassPathResource("vendors/references/lib.zip/libri-testfile.zip").getFile();
// final GenericFile<File> genericFile =
// FileConsumer.asGenericFile(file.getParent(), file, StandardCharsets.UTF_8.name(), false);
//
// final String uri = libFtpConfiguration.getFtpEndpoint();
// producer.sendBodyAndHeaders(uri, InOut, genericFile, headers);
// test if entry was made in the database
final List<ImportedLibFilename> filenames = importedLibFilenameRepository.findAll();
assertThat(filenames).usingElementComparatorIgnoringFields("id", "timestamp")
.containsExactly(expectedFilename("libri-testfile.zip"));
// test if content of unzipped file is valid
final String expected = unzipped + "/libri-testfile.xml";
final Path targetFile = Paths.get(expected);
final byte[] encoded = Files.readAllBytes(targetFile);
final String actualFileContent = new String(encoded, Charset.defaultCharset());
final String expectedFileContent = "This is my little test file for Libri import";
assertThat(actualFileContent).isEqualTo(expectedFileContent);
}
private ImportedLibFilename expectedFilename(final String filename) {
final ImportedLibFilename entity = new ImportedLibFilename();
entity.setFilename(filename);
return entity;
}
问题是:
所有骆驼路线都是自动启动的,因为我将文件复制到 FTP,所以测试是绿色的。 但是我的测试中有一个#sleep,我不想要它。 我不希望骆驼路线开始,只开始我需要的路线。
我的问题是:
.autoStartup(yourVariable)
以使其启动可配置。 在正常环境中将变量设置为true
,在测试用例中设置为false
。 例如将路由拆分为FTP 和处理路由。 第一个只做 FTP 传输,然后将接收到的消息发送到处理路由(例如direct:
路由)。
好处:
direct:
处理路径的端点来轻松测试处理路径。 测试也可以专注于一件事。当你真的想测试从 FTP 文件下降到最后的整个过程时,考虑使用Citrus 测试框架或类似的工具。 骆驼路线测试(在我看来)是一种“骆驼路线的单元测试”,而不是完整的集成测试。
感谢@burki ...
他建议拆分路线(单一职责)帮助我解决了我的问题:
这是路线:
从 sFTP 消耗的“主路由”:
@Override
public void configure() throws Exception {
// @formatter:off
from(endpoint)
.setHeader("Address", constant(address))
.log(INFO, "Import Libri changeset: Consuming from '${headers.Address}' the file '${headers.CamelFileName}'.")
.to("direct:import-new-file");
// @formatter:on
}
第一条子路线:
@Override
public void configure() throws Exception {
// @formatter:off
from("direct:import-new-file")
.choice()
.when(method(isFilenameAlreadyImported))
.log(TRACE, "'${headers.CamelFileName}' is already imported.")
.endChoice()
.otherwise()
.log(TRACE, "Import file '${headers.CamelFileName}'.")
.multicast()
.to("direct:persist-filename", "direct:unzip-file")
.endChoice()
.end()
.end();
// @formatter:on
}
两个多播:
@Override
public void configure() throws Exception {
// @formatter:off
from("direct:persist-filename")
.log(TRACE, "Try to write filename '${headers.CamelFileName}' to database.")
.bean(method(persistFilename))
.end();
// @formatter:on
}
和
@Override
public void configure() throws Exception {
// @formatter:off
from("direct:unzip-file")
.log(TRACE, "Try to unzip file '${headers.CamelFileName}'.")
.bean(method(unzipFile))
.end();
// @formatter:on
}
使用此设置,我可以编写如下测试:
@Test
public void testRoute_validExtractedFile() throws Exception {
final File source = ZIP_FILE_RESOURCE.getFile();
producer.sendBodyAndHeaders(URI, InOut, source, headers());
final String actual = getFileContent(unzippedPath, FILENAME);
final String expected = "This is my little test file for Libri import";
assertThat(actual).isEqualTo(expected);
}
@Test
public void testRoute_databaseEntryExists() throws Exception {
final File source = ZIP_FILE_RESOURCE.getFile();
producer.sendBodyAndHeaders(URI, InOut, source, headers());
final List<ImportedFilename> actual = importedFilenameRepository.findAll();
final ImportedFilename expected = importedFilename(ZIPPED_FILENAME);
assertThat(actual).usingElementComparatorIgnoringFields("id", "timestamp")
.containsExactly(expected);
}
private String getFileContent(final String path, final String filename) throws IOException {
final String targetFile = path + "/" + filename;
final byte[] encodedFileContent = Files.readAllBytes(Paths.get(targetFile));
return new String(encodedFileContent, Charset.defaultCharset());
}
private Map<String, Object> headers() {
final Map<String, Object> headers = Maps.newHashMap();
headers.put("CamelFileName", ZIPPED_FILENAME);
return headers;
}
我可以使用ProducerTemplate
(生产者)启动骆驼路线并将消息发送到直接端点(而不是 ftp 端点)。
