1@initClass("org.evomaster.client.java.controller.internal.db.h2.DatabaseH2TestInit")2class FooTest {3    void testFoo(){4    }5}6The @initClass annotation is used to specify the class that contains the method to initialize the database. In this case, we use the DatabaseH2TestInit class, which is provided by EvoMaster. The method to initialize the database is called initDatabase() , and it is declared as follows:7public static void initDatabase() {8    try (Connection con = DriverManager.getConnection("jdbc:h2:mem:TEST;DB_CLOSE_DELAY=-1", "sa", "")) {9        String sql = "CREATE TABLE IF NOT EXISTS Foo (id INTEGER, name VARCHAR(255))";10        try (PreparedStatement ps = con.prepareStatement(sql)) {11            ps.execute();12        }13        sql = "INSERT INTO Foo VALUES(1, 'foo1')";14        try (PreparedStatement ps = con.prepareStatement(sql)) {15            ps.execute();16        }17        sql = "INSERT INTO Foo VALUES(2, 'foo2')";18        try (PreparedStatement ps = con.prepareStatement(sql)) {19            ps.execute();20        }21    } catch (SQLException e) {22        throw new RuntimeException(e);23    }24}25void testFoo(){26    Foo foo = new Foo();27    foo.setId(1);28    foo.setName("foo1");29    Foo foo2 = fooDAO.find(foo);30    assertNotNull(foo2);31    assertEquals(1, foo2.getId());32    assertEquals("foo1", foo2.getName());33}34The test case creates a Foo object and sets the id and name properties. It then calls the find() method of the FooDAO class, which is the DAO class of the Foo class. The find() method uses the database to retrieve the Foo object from the database. If the find() method works properly, it should return a Foo object with the same id and name properties as the Foo object that was passed as a parameter to the method
