Pergunta
Em grunhido, executamos testes de unidade em PhantomJs seguindo os seguintes caminhos.
karma: {
options: {
configFile: 'karma.conf.js',
runnerPort: 9876,
browsers: ['Chrome']
},
unitTestDev: {
browsers: ['PhantomJS'],
singleRun: true
}
}
grunt.registerTask('unitTest',['karma:unitTestDev']);
Aqui está o arquivo karma.conf.js.
// Karma configuration

module.exports = function(config) {
config.set({

basePath: '',
// frameworks to use

// list of files / patterns to load in the browser

singleRun: false
});
};
Ao executar o comando "karma:unitTestDev", recebo os seguintes erros.
Running "karma:unitTestDev" (karma) task

Estamos enfrentando o problema acima nos sistemas operacionais Windows e Linux.No Mac, o karma executa testes com sucesso no PhantomJS.
No Windows, se executarmos o teste acima no navegador Chrome, em vez do PhantomJS, o karma executará com sucesso todos os testes de unidade.
Aqui estão as dependências relacionadas ao carma em Package.json
"phantomjs": "~1.9.7-3",
"karma": "~0.12.3",
"karma-chrome-launcher": "~0.1.3",
"karma-jasmine": "~0.1.5",
"karma-html-reporter": "~0.2.3",
"karma-junit-reporter": "~0.2.1",
"grunt-karma": "~0.8.2",
"karma-phantomjs-launcher": "~0.1.3"
Deixe-me saber se há algum problema conhecido de carma ou grunhido com o PhantomJS.
Solução
Há um problema com o "Karma-phantomjs-launcher" v0.1.3.Mude para v0.1.4 e então funcionará bem.
