本文介紹了在?Spring?Boot?應(yīng)用中使用Flapdoodle?Embed?Mongo進(jìn)行?MongoDB?測(cè)試的方法,包括Embed?Mongo?的概念,添加依賴(lài)、配置、運(yùn)行測(cè)試的步驟,還列舉了其優(yōu)勢(shì)如快速啟動(dòng)關(guān)閉、環(huán)境一致、無(wú)需外部依賴(lài)等,以及注意事項(xiàng)和結(jié)論,需要的朋友可以參考下

在現(xiàn)代應(yīng)用開(kāi)發(fā)中，數(shù)據(jù)庫(kù)是不可或缺的一部分。對(duì)于使用 MongoDB 的 Java 應(yīng)用，進(jìn)行單元測(cè)試時(shí)，通常需要一個(gè)輕量級(jí)的數(shù)據(jù)庫(kù)實(shí)例。de.flapdoodle.embed.mongo 是一個(gè)非常有用的庫(kù)，它允許開(kāi)發(fā)者在測(cè)試中嵌入 MongoDB 實(shí)例，而無(wú)需在本地或 CI 環(huán)境中安裝 MongoDB。本文將介紹如何在 Spring Boot 應(yīng)用中使用 Flapdoodle Embed Mongo。

1. 什么是Embed Mongo？

Embed Mongo 是一個(gè)用于在 Java 應(yīng)用中嵌入 MongoDB 的庫(kù)。它可以在測(cè)試期間啟動(dòng)和停止 MongoDB 實(shí)例，確保測(cè)試環(huán)境的干凈和一致性。這個(gè)庫(kù)特別適合于單元測(cè)試和集成測(cè)試，因?yàn)樗梢钥焖賳?dòng)和關(guān)閉 MongoDB 實(shí)例。

2. 添加依賴(lài)

在使用 Flapdoodle Embed Mongo 之前，需要在 Maven 項(xiàng)目的 pom.xml 文件中添加相關(guān)依賴(lài)：

<?xml version="1.0" encoding="UTF-8"?>

    </dependencies>
</project>

3. 配置嵌入式 MongoDB

在測(cè)試類(lèi)中配置嵌入式 MongoDB。以下是一個(gè)示例代碼，展示了如何在 JUnit 測(cè)試中使用 Flapdoodle Embed Mongo：

package com.et;

import org.bson.Document;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.test.autoconfigure.data.mongo.AutoConfigureDataMongo;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.test.annotation.DirtiesContext;
import org.springframework.test.context.ContextConfiguration;

import static org.assertj.core.api.Assertions.as;
import static org.assertj.core.api.Assertions.assertThat;
import static org.assertj.core.api.InstanceOfAssertFactories.LIST;
import static org.assertj.core.api.InstanceOfAssertFactories.MAP;

@AutoConfigureDataMongo
@SpringBootTest(
   properties = {
      "de.flapdoodle.mongodb.embedded.version=4.4.18",
      "spring.data.mongodb.username=customUser",
      "spring.data.mongodb.password=userPassword123",
   }
)
@EnableAutoConfiguration
@DirtiesContext
public class AuthTest {

   @Test
   void example(@Autowired final MongoTemplate mongoTemplate) {
      assertThat(mongoTemplate.getDb()).isNotNull();

      mongoTemplate.getDb().getCollection("first").insertOne(new Document("value","a"));
      mongoTemplate.getDb().getCollection("second").insertOne(new Document("value","b"));

      Document result = mongoTemplate.getDb().runCommand(new Document("listCollections", 1));
      assertThat(result).containsEntry("ok", 1.0);
      assertThat(result)
         .extracting(doc -> doc.get("cursor"), as(MAP))
         .containsKey("firstBatch")
         .extracting(cursor -> cursor.get("firstBatch"), as(LIST))
         .hasSize(2)
         .anySatisfy(collection -> assertThat(collection)
            .isInstanceOfSatisfying(Document.class, col -> assertThat(col)
               .extracting(c -> c.get("name")).isEqualTo("first")))
         .anySatisfy(collection -> assertThat(collection)
            .isInstanceOfSatisfying(Document.class, col -> assertThat(col)
               .extracting(c -> c.get("name")).isEqualTo("second")));
   }

}

@AutoConfigureDataMongo：自動(dòng)配置 MongoDB 數(shù)據(jù)庫(kù)，適用于測(cè)試環(huán)境。
@SpringBootTest：標(biāo)記這個(gè)類(lèi)為 Spring Boot 測(cè)試類(lèi)，允許加載 Spring 上下文。properties 屬性用于設(shè)置嵌入式 MongoDB 的版本和數(shù)據(jù)庫(kù)的用戶(hù)名、密碼。
@EnableAutoConfiguration：?jiǎn)⒂?Spring Boot 的自動(dòng)配置功能。
@DirtiesContext：在測(cè)試后重置 Spring 上下文，以確保每個(gè)測(cè)試都有一個(gè)干凈的上下文。

以上只是一些關(guān)鍵代碼。

4. 運(yùn)行測(cè)試

運(yùn)行測(cè)試類(lèi)，返回日志如下

快速啟動(dòng)和關(guān)閉：嵌入式 MongoDB 可以快速啟動(dòng)和關(guān)閉，適合于頻繁的測(cè)試。
環(huán)境一致性：每次測(cè)試都在一個(gè)干凈的數(shù)據(jù)庫(kù)環(huán)境中運(yùn)行，避免了數(shù)據(jù)污染。
無(wú)需外部依賴(lài)：不需要在本地或 CI 環(huán)境中安裝 MongoDB，減少了環(huán)境配置的復(fù)雜性。

5. 注意事項(xiàng)

確保使用的 MongoDB 版本與生產(chǎn)環(huán)境中的版本兼容。
根據(jù)需要調(diào)整 MongoDB 的配置，例如端口、數(shù)據(jù)庫(kù)名稱(chēng)等。

結(jié)論

Flapdoodle Embed Mongo 是一個(gè)強(qiáng)大的工具，可以幫助開(kāi)發(fā)者在 Java 應(yīng)用中輕松地進(jìn)行 MongoDB 測(cè)試。通過(guò)嵌入式 MongoDB，開(kāi)發(fā)者可以確保測(cè)試的可靠性和一致性，從而提高開(kāi)發(fā)效率。希望本文能幫助你在項(xiàng)目中順利集成和使用 Flapdoodle Embed Mongo。

以上就是SpringBoot3.x嵌入MongoDB進(jìn)行測(cè)試的步驟詳解的詳細(xì)內(nèi)容，更多關(guān)于SpringBoot3.x嵌入MongoDB的資料請(qǐng)關(guān)注腳本之家其它相關(guān)文章！
