### Question:
ContrailPolicyRefSeq { @Override public String toString() { return "ContrailPolicyRefSeq [major=" + major + ", minor=" + minor + "]"; } ContrailPolicyRefSeq();  ContrailPolicyRefSeq(String major, String minor); String getMajor(); void setMajor(String major); String getMinor(); void setMinor(String minor); @Override String toString();  }### Answer:
@Test public void ContrailPolicyRefSeqJson_Test() { ContrailPolicyRefSeq cprs = new ContrailPolicyRefSeq("majorVersion 1", "minorVersion 0.02"); assertTrue(cprs.toString().contains("majorVersion 1")); assertTrue(cprs.toString().contains("minorVersion 0.02")); }
