I am creating unit tests but the class uses objects that have long JSON. What can I do to improve the readability of this?In tests, only insert those JSON really needed for the test. The class I tested is responsible in turn that JSON in a modified spreadsheet (xlsx) and it seems difficult to maintain the code.@Testpublic void testBuildSheet_validSheet_NoMedia() throws Exception {    BasicDBObject specPlanilha = (BasicDBObject) JSON.parse({\spec_veiculo\ : \BuscaDescontos\ , \spec_canal\ : \Homepage\ , \spec_formato\ : \SuperBanner\ , \spec_linha-criativa\ :  null  ,  +            \spec_tamanho\ : \728x90\ , \spec_extensao\ : \jpg/png\ , \peca_peso\ : \50kb\ , \imagem_peso\ : \50kb\ ,  +            \peca_flash\ : \4 at 10\ , \peca_clicktag\ : \on (release) {\\n  getURL(_root.clickTAG, '_blank');\\n}\ ,  +            \peca_framerate\ : \24fps\ , \peca_tempo\ : \30s\ , \spec_observacoes\ :  null  ,  +            \peca_nome\ : \Whirlpool_LinhaBranca_BuscaDescontos_Homepage_SuperBanner_-.jpg\ , \extras\ :  +            { \linha\ : \10\ , \Rich Media\ : \No\ , \Link Especificao\ : \http://portal.agenciaclick.com.br/midiaSP/Midia/Lists/Tabela%20de%20Especificao%20e%20Formato%20de%20Peas/DispForm.aspx?ID=3405&Source=http%3A%2F%2Fportal%2Eagenciaclick%2Ecom%2Ebr%2FmidiaSP%2FMidia%2FLists%2FTabela%2520de%2520Especificao%2520e%2520Formato%2520de%2520Peas%2FSites%2Easpx\ , +             \Data Entrega Mdia\ :  null  , \Data Disparo/Subida\ :  null }});    List<BasicDBObject> listSpec = new ArrayList<>();    listSpec.add(specPlanilha);    BasicDBObject specFields = (BasicDBObject) JSON.parse({\peca_nome\: \Whirlpool_LinhaBranca_BuscaDescontos_Homepage_SuperBanner_-.jpg\,\n +                  \extras\: {\n +                    \linha\: \10\,\n +                    \Rich Media\: \No\,\n +                    \Link Especificao\: \http://portal.agenciaclick.com.br/midiaSP/Midia/Lists/Tabela%20de%20Especificao%20e%20Formato%20de%20Peas/DispForm.aspx?ID=3405&Source=http%3A%2F%2Fportal%2Eagenciaclick%2Ecom%2Ebr%2FmidiaSP%2FMidia%2FLists%2FTabela%2520de%2520Especificao%2520e%2520Formato%2520de%2520Peas%2FSites%2Easpx\,\n +                    \Data Entrega Mdia\: null,\n +                    \Data Disparo/Subida\: null\n +                  }});    ValidacaoResultado myValidation = new ValidacaoResultado().setId(123)            .setResultadoConsolidado(NO_MEDIA)            .setResultado(new BasicDBObject())            .setSpec(specFields);    oknok.validacao.entities.Planilha planilha = new Planilha()            .setPath(PlanilhaWorkbook.class.getClass().getResource(/planilhaWorkbook/T001.xlsx).getPath())            .setNomeHash(noMediaTest.xlsx)            .setSpec(listSpec);    List<ValidacaoResultado> myList = new ArrayList<>();    myList.add(myValidation);    File actual = planilhaWorkbook.buildSheet(myList, planilha);    SoftAssertions soft = new SoftAssertions();    soft.assertThat(actual.getName()).isEqualTo(planilha.getNomeHash());    soft.assertAll();}
