- It keeps the specific test logic separated from the common test logic.
- You can run those tests in parallel to other projects of the build.

#### Using test fixtures

Sometimes we want to share test fixtures to setup the code under test across multiple projects. There are basically two ways doing so.

import org.elasticsearch.common.breaker.NoopCircuitBreaker;
import org.elasticsearch.common.lucene.search.TopDocsAndMaxScore;
import org.elasticsearch.index.Index;
import org.elasticsearch.index.shard.ShardId;
import org.elasticsearch.indices.breaker.NoneCircuitBreakerService;
import org.elasticsearch.search.DocValueFormat;
import org.elasticsearch.search.SearchShardTarget;

    }

    @Test
    void testToStringWithDifferentPaths() {
        // Test with various path formats
        String[] testPaths = { "simple.txt", "path/to/file.doc", "//server/share/file.txt", "folder\\windows\\style.txt", "" // empty path
        };

        for (String path : testPaths) {
            trans2QueryPathInfo = new Trans2QueryPathInformation(config, path, TEST_INFO_LEVEL);

    /**
     * SMB command to close a find operation.
     */
    public static final byte SMB_COM_FIND_CLOSE2 = (byte) 0x34;

    /**
     * SMB command to disconnect from a tree share.
     */
    public static final byte SMB_COM_TREE_DISCONNECT = (byte) 0x71;

    /**
     * SMB command to negotiate protocol dialect.
     */
    public static final byte SMB_COM_NEGOTIATE = (byte) 0x72;

public void testRdmaLargeFileTransfer() throws Exception {
    CIFSContext context = getTestContext();
    context.getConfig().setProperty("jcifs.smb.client.useRDMA", "true");
    
    SmbFile file = new SmbFile("smb://server/share/largefile.dat", context);
    
    // Measure RDMA transfer performance
    byte[] data = new byte[10485760];  // 10MB
    Arrays.fill(data, (byte)0x42);
    
    long start = System.currentTimeMillis();
    

    void getDfsReferrals_happy() throws Exception {
        when(transport.getDfsReferrals(any(), any(), any(), any(), anyInt())).thenReturn(referral);

        String name = "\\\\server\\\\share\\\\path"; // UNC-like DFS path
        String host = "server.example";
        String domain = "EXAMPLE";
        int rn = 0;

        jcifs.DfsReferralData result = transport.getDfsReferrals(ctx, name, host, domain, rn);

There's a high chance that the logic for your *startup* and *shutdown* is connected, you might want to start something and then finish it, acquire a resource and then release it, etc.

Doing that in separated functions that don't share logic or variables together is more difficult as you would need to store values in global variables or similar tricks.

Because of that, it's now recommended to instead use the `lifespan` as explained above.
