## Usage
### JVM annotations
```java
@MeasureHeapAllocation
@HeapSize(value = 1, unit = AllocationUnit.GIGA_BYTE)
@Test
public void execute_batch() {
...
}
```
📙 [All the JVM annotations](https://github.com/quick-perf/doc/wiki/JVM-annotations) :mag_right: Examples with [JUnit4](https://github.com/quick-perf/quickperf-examples/blob/master/jvm-junit4/src/test/java/org/quickperf/jvm/JvmAnnotationsJunit4Test.java), [Junit5](https://github.com/quick-perf/quickperf-examples/blob/master/jvm-junit5/src/test/java/org/quickperf/jvm/JvmAnnotationsJunit5Test.java), [TestNG](https://github.com/quick-perf/quickperf-examples/blob/master/jvm-testng/src/test/java/org/quickperf/jvm/JvmAnnotationsTestNGTest.java) :mag_right: [Heap allocation of Apache Maven](https://github.com/quick-perf/maven-test-bench)
### **SQL annotations**
```java
@ExpectSelect(1)
@Test
public void should_find_all_players() {
...
}
```
```
[PERF] You may think that <1> select statement was sent to the database
But there are in fact <10>...
💣 You may have even more select statements with production data.
Be careful with the cost of JDBC roundtrips: https://blog.jooq.org/2017/12/18/the-cost-of-jdbc-server-roundtrips/
```
Auto-detection of Hibernate and Spring Data JPA:
```
💡 Perhaps you are facing an N+1 select issue
* With Hibernate, you may fix it by using JOIN FETCH
or LEFT JOIN FETCH
or FetchType.LAZY
or ...
```
```
* With Spring Data JPA, you may fix it by adding @EntityGraph(attributePaths = { "..." })
on repository method: https://docs.spring.io/spring-data/jpa/docs/current/reference/ht
