The steps below show how to use this notification target in `namespace` format. The other format is very similar and is omitted for brevity.

### Step 1: Ensure Elasticsearch minimum requirements are met

    @Test
    public void test_convertPhraseQuery_longPhrase() {
        // Test with long phrase (many terms)
        PhraseQuery.Builder builder = new PhraseQuery.Builder();
        String[] words = { "this", "is", "a", "very", "long", "phrase", "query" };
        for (String word : words) {
            builder.add(new Term(Constants.DEFAULT_FIELD, word));
        }
        PhraseQuery phraseQuery = builder.build();

        assertEquals("value0", param.getValues()[0]);
        assertEquals("value999", param.getValues()[999]);
    }

    @Test
    public void test_veryLongStrings() {
        // Test with very long strings
        StringBuilder longNameBuilder = new StringBuilder();
        for (int i = 0; i < 10000; i++) {
            longNameBuilder.append("a");
        }
        String longName = longNameBuilder.toString();

        // Writer thread sets alive to false early
        Thread writerThread = new Thread(() -> {
            try {
                startLatch.await(); // Wait for start signal
                // Set alive to false very early - no delay
                dataStore.alive = false;
            } catch (InterruptedException e) {
                Thread.currentThread().interrupt();
            }
        });
        writerThread.start();

            assertNotNull(results);
        }
    }

    /**
     * Test handling of very slow searcher (simulates timeout scenario).
     */
    @Test
    public void test_slowSearcher() throws Exception {
        try (RankFusionProcessor processor = new RankFusionProcessor()) {

        assertTrue(toStringResult.contains(SsoLoginException.class.getName()));
        assertTrue(toStringResult.contains(message));
    }

    @Test
    public void test_longMessage() {
        // Test with very long message
        StringBuilder longMessage = new StringBuilder();
        for (int i = 0; i < 1000; i++) {
            longMessage.append("Long SSO error message part ").append(i).append(" ");
        }

        helper.delayByRules();
        end = System.currentTimeMillis();
        assertTrue(end - start < 50); // Should return quickly

        // Test with rule that has delay (we'll use a very short delay for testing)
        helper.ruleList.clear();
        helper.addIntervalRule("12:00", "13:00", "*", 10);
        start = System.currentTimeMillis();
        helper.delayByRules();

        Smb2LeaseKey key = leaseManager.requestLease(path, requestedState);
        assertNotNull(leaseManager.getLease(key));

        // Wait a bit and then cleanup with a very short expiration time
        Thread.sleep(10);
        int cleaned = leaseManager.cleanupExpiredLeases(1); // 1ms expiration

You can also read more about them in the [Wikipedia for Environment Variable](https://en.wikipedia.org/wiki/Environment_variable).

In many cases it's not very obvious how environment variables would be useful and applicable right away. But they keep showing up in many different scenarios when you are developing, so it's good to know about them.
