java - 测试在 IDE 中通过但在 TeamCity 中失败

Question

我有一个必须测试的类(class):

package com.mycompany.openapi.cms.core.support.liquibase;

import liquibase.change.custom.CustomTaskChange;
import liquibase.database.Database;
import liquibase.database.jvm.JdbcConnection;
import liquibase.exception.CustomChangeException;
import liquibase.exception.SetupException;
import liquibase.exception.ValidationErrors;
import liquibase.resource.ResourceAccessor;
import org.slf4j.LoggerFactory;
import org.springframework.util.StringUtils;

import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.sql.Statement;
import java.util.Set;

public class ApplySqlFileIfExistsChange implements CustomTaskChange {

    private final org.slf4j.Logger logger = LoggerFactory.getLogger(getClass());

    private String file;
    private ResourceAccessor resourceAccessor;

    @Override
    public void execute(Database database) throws CustomChangeException {
        JdbcConnection databaseConnection = (JdbcConnection) database.getConnection();
        try {
            Set<InputStream> files = resourceAccessor.getResourcesAsStream(file);
            if(files != null){
                for (InputStream inputStream : files) {
                    BufferedReader in = new BufferedReader(
                            new InputStreamReader(inputStream));
                    String str;
                    String sql;
                    StringBuilder sqlBuilder = new StringBuilder("");
                    while ((str = in.readLine()) != null) {
                        sqlBuilder.append(str).append(" ");
                    }
                    in.close();
                    sql = sqlBuilder.toString().trim();
                    if(StringUtils.isEmpty(sql)){
                        return;
                    }
                    Statement statement = databaseConnection.createStatement();
                    statement.execute(sql);
                    statement.close();
                }
            }
        } catch (FileNotFoundException e) {
            logger.error(e.getMessage(), e);
        } catch (Exception e) {
            throw new CustomChangeException(e);
        }
    }

    public String getFile() {
        return file;
    }

    public void setFile(String file) {
        this.file = file;
    }

    @Override
    public void setFileOpener(ResourceAccessor resourceAccessor) {
        this.resourceAccessor = resourceAccessor;
    }
}

我写了测试:

package com.mycompany.openapi.cms.core.support.liquibase;

import com.google.common.collect.Sets;
import liquibase.database.Database;
import liquibase.database.jvm.JdbcConnection;
import liquibase.resource.ResourceAccessor;
import org.junit.Before;
import org.junit.BeforeClass;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import java.io.ByteArrayInputStream;
import java.io.InputStream;
import java.nio.charset.StandardCharsets;
import java.sql.Statement;

import static org.mockito.Matchers.anyString;
import static org.mockito.Mockito.verify;
import static org.powermock.api.mockito.PowerMockito.*;

@RunWith(PowerMockRunner.class)
@PrepareForTest({LoggerFactory.class})
public class TestApplySqlFileIfExistsChange {

    @InjectMocks
    ApplySqlFileIfExistsChange applySqlFileIfExistsChange;

    @Mock
    private ResourceAccessor resourceAccessor;

    @Mock
    private JdbcConnection jdbcConnection;

    @Mock
    private Database database;

    @Mock
    Statement statement;

    @BeforeClass
    public static void setUpClass() {
        mockStatic(LoggerFactory.class);
        when(LoggerFactory.getLogger(ApplySqlFileIfExistsChange.class)).thenReturn(mock(Logger.class));
    }

    @Before
    public void setUp() throws Exception {
        when(database.getConnection()).thenReturn(jdbcConnection);

        InputStream inp1, inp2;
        inp1 = new ByteArrayInputStream("FirstTestQuery".getBytes(StandardCharsets.UTF_8));
        inp2 = new ByteArrayInputStream("SecondTestQuery".getBytes(StandardCharsets.UTF_8));

        when(resourceAccessor.getResourcesAsStream(anyString())).thenReturn(Sets.newHashSet(inp1, inp2));
        when(jdbcConnection.createStatement()).thenReturn(statement);
    }

    @Test
    public void execute() throws Exception {
        applySqlFileIfExistsChange.execute(database);
        verify(statement).execute("FirstTestQuery");
        verify(statement).execute("SecondTestQuery");
    }

}

问题是上面的测试在我的 IDE 中通过了，但是当我在存储库中进行推送时，TeamCity 构建在我的测试中失败了。我不明白为什么，因为两个地方的代码都一样。这是 TeamCity 中的堆栈跟踪:

对于问题中的代码数量，我深表歉意。

您的 Powermock/Mockito 版本可能存在冲突。检查您本地的 Maven 仓库的版本，并删除旧版本在您的 pom 中和/或更新包含它的其他依赖项。

检查项目的根目录:

mvn dependency:tree -Dverbose -Dincludes=NAME_OF_DEPENDENCY
