testing - Neo4j程序测试和测试服务器

问题描述

我正在创建一个 Neo4J 程序来导入 RDF 数据。RDF 数据有一些复杂的结构信息，我编写了测试来涵盖每种情况（一些三元组创建标签、一些属性、一些关系......等等）。

这些过程是用 Kotlin 编写的。

它工作正常，实际上每个测试在单独执行时都会成功。但是当我一次运行整个测试用例时，我获得了一次成功，然后所有其他测试都失败了，但有以下例外：

org.neo4j.kernel.impl.core.ThreadToStatementContextBridge$BridgeDatabaseShutdownException: This database is shutdown.

我是 Neo4J 的新手，我很难找到好的例子，这里是一个测试用例的结构：

package mypackage

import org.junit.Assert
import org.junit.Rule
import org.junit.Test
import org.neo4j.driver.internal.value.NullValue

import org.neo4j.driver.v1.Config
import org.neo4j.driver.v1.GraphDatabase
import org.neo4j.harness.junit.Neo4jRule

import java.io.File
import java.net.URI

class PropertyParserTest {

    // this rule starts a Neo4j instance
    @Rule
    @JvmField
    var neo4j: Neo4jRule = Neo4jRule()
            // This is the procedure/function to test
            .withProcedure(Mypackage::class.java)

    @Test
    @Throws(Throwable::class)
    fun shouldSetTheNameCorrectly() {

        GraphDatabase.driver(neo4j.boltURI(), Config.build().withoutEncryption().toConfig()).use({ driver ->
            driver.session().use({ session ->
                // Given
                val path: String = File("src/test/resources/test_rdf__1.ttl").getAbsolutePath()
                val testFile = File(path)
                val urlTestFile: URI = testFile.toURI()
                session.run("CALL mypackage.import('${urlTestFile}')")

                // When
                val result = session.run("MATCH (n) WHERE n:Person RETURN n.name as name")

                // Then
                var rec = result.next()
                Assert.assertEquals("Manuel, Niklaus (Niclaus)", rec.get("name").asString())
                rec = result?.next()
                Assert.assertEquals("Fischli / Weiss", rec.get("name").asString())
                rec = result?.next()
                Assert.assertEquals("Hodler, Ferdinand", rec.get("name").asString())
            })
        })
    }

    @Test
    @Throws(Throwable::class)
    fun shouldSetTheAlternateNameCorrectly() {

        GraphDatabase.driver(neo4j?.boltURI(), Config.build().withoutEncryption().toConfig()).use({ driver ->
            driver.session().use({ session ->
                // Given
                val path: String = File("src/test/resources/test_rdf_2.ttl").absolutePath
                val testFile = File(path)
                val urlTestFile: URI = testFile.toURI()
                session.run("CALL mypackage.import('${urlTestFile}')")

                // When
                val result = session.run("MATCH (n) WHERE n:Person RETURN n.name as name, n.alternate_names as alternate_names")

                // Then
                var rec = result.next()
                Assert.assertEquals("Holbein, Hans", rec.get("name").asString())
                var alternateNames = rec.get("alternate_names").asList()
                Assert.assertEquals(9, alternateNames.size)
                Assert.assertEquals("Holpenius, Joannes", alternateNames[0])
                Assert.assertEquals("Olpenius, Hans", alternateNames[8])

                rec = result.next()
                Assert.assertEquals("Manuel, Niklaus (Niclaus)", rec.get("name").asString())
                alternateNames = rec.get("alternate_names").asList()
                Assert.assertEquals(8, alternateNames.size)
                rec = result.next()
                Assert.assertEquals("Fischli / Weiss", rec.get("name").asString())
                Assert.assertTrue(rec.get("alternate_names") is NullValue)

                rec = result.next()
                Assert.assertEquals("Hodler, Ferdinand", rec.get("name").asString())
                Assert.assertTrue(rec.get("alternate_names") is NullValue)

                rec = result.next()
                Assert.assertEquals("Holbein", rec.get("name").asString())
                alternateNames = rec.get("alternate_names").asList()
                Assert.assertEquals(3, alternateNames.size)

            })
        })    
    }    
}

任何想法？我使用这个代码库作为起点：https ://github.com/jbarrasa/neosemantics/blob/3.3/src/test/java/semantics/RDFImportTest.java
